feeling very hurt 😔 (long read needed to vent)

Anna • Hi! My name is Anna ! I`m 33 and I just had my rainbow baby July 5 2017! Enjoying life and undecided on future children! 👶🏼👶🏼💙💙
So my fiancé and I have been together for almost 4 years and engaged for about 7 months now! I only have 1 brother and this weekend was his boys get away bachelor weekend in which he invited all of his buddies and wedding party to go to... now heres why I'm upset.. about 5 weeks ago he approached my fiancé and told him dude your def invited to my Bach party as soon as we know more details you will def know... well the closer we got to the wedding the weirder it got that my fiancé hadn't heard a thing about this weekend and I honestly had no idea when it was so I assumed it was prob the weekend of June 3rd... the reason I thought this is because that's when his fiancée bachelorette party is which I am invited to as well... I had the details and I decided not to go because I'm pregnant almost 8 months and I don't feel safe and to be honest the bride was relieved when I said I didn't want to attend she felt the same way and I was ok with it... anyways my fiancé started to say I don't understand why I don't have any details I don't think I'm really invited and I kept saying yes you are my brother told you they prob haven't set anything in stone... honestly I was clueless... well I just so happen to work with the girl who I set my cousin up with who is my brothers best man! We are friends as well...Here's sketchiness number one she always asks me to hang out whenever her bf is not around and yet not once did she even ask me if I wanted to hang out this weekend or once mention anything about the Bach party ?? Especially knowing her bf was planning it... I'm a hairdresser as is she and yesterday my mother walks in to get her hair colored and I happen to have tried to text my bro yesterday about helping with my baby shower and he didnt respond so I asked my mother why?? So innocently my mother goes oh that's because he's at his bachelor weekend in Atlantic City... 😲😮😱... I was like whatttttttttttttty?????????????????? Mom please tell me your joking ?! She goes why what's the big deal ? So I go mom my bro Sal is his name told Jared (fiancé) that he was invited to the Bach party this obvi means he's not.. her eyes popped and she agreed it was wrong...omg what am I going to tell him.. he has been constantly asking me about it for the past few weeks he's going to be heart broken 😔!  My friend happens to be two chairs away and hears everything I'm saying and I hear her get totally silent as if oh shit the cat is out of the bag she was totally caught when she prob was hoping I wouldn't find out! So I don't say nothing to her and I leave work that day and go home not sure what I'm going to say to my fiancé.. as I walk in the door I realize I had to say nothing ... he went over a diff cousin of mine earlier who was also not invited and hurt as well and told him the whole story.... so now my fiancé goes why would your brother invite me and then not tell me anything ?? I could tell he was heart broken ... so I go honestly babe I have no idea but I doubt it's his fault usually the best man makes the plans... he then goes does your brother hate me and I said no why would you say that he loves you... so immediately he goes i bet it's your cousin (best mans fault) and honestly I believe the same thing ... ever since I met my fiancé my cousin has never liked him because apparently his cheating ex gf who slept with prob 20 man behind his back also happens to have dated my fiancé during her cheating times... ok and honestly who fuckin cares it's not like my fiancé did it to hurt him he didn't even know she wasn't single or that my cousin was my cousin or that we would meet in the future... he was played by her as well they actually have something in common but instead he has basically shunned him since we met... my fiancé has tried to talk to him about it even aologized when he didn't have to, makes an effort to always say high shake his hand and treat him with respect even though he doesn't get it in return... but to not invite him to my only brothers Bach party is just a slap in the face to me and to him and enough is enough already this is too far!!! So now it's today I go to work and I say something to my friend the one I work with that dates my cousin, all I say is omg i had no clue it was Sals Bach party this weekend Jared was so hurt last night I can't believe that he wasn't invited I'm hurt too .. her response was well I hope you don't think Joey (the cousin) had anything to do with it because I bet you do but your bro is the one who was in charge... hmm that's weird being that her and I were good friends it's funny that I knew nothing she never mentioned it kept it quiet and is now just saying something.. I didn't want to be unprofessional at work so I dropped it ... I go home and now I see numerous posts all over fb that there are not only just his close buddies and wedding party invited but random fuckin other guys as well now I'm fuming... 😤😤😤... My fiancé comes home from work and goes I think I want to text your brother and say sorry I'm not there I wasn't told any info and I would of been there if someone told me so I hope you don't think I dissed you .. I honestly almost started to cry because my fiancé thinks so highly of my bro and that it's not his fault that he wanted to apologize when it should be the other way around... and now my coworker has me thinking it is my bros fault...so he leaves to go have dinner with his friends and I decide to write my bro a nice long text about basically how messed up it this whole situation is, how hurt Jared is and some of the other family members that they weren't invited and that he better lie and say he didn't plan it so no one is hurt... id rather him lie and save his relationship with my fiancé then tell the truth and potentially ruin the good repore they have...I also tell him I'm hurt being his only sister should have been enough of a reason to invite him...I then call my father I just needed to talk to someone and that's when I found out my coworker friend is such a liar and was trying to cover her own ass, he told me Joey the cousin and one other guy in the wedding party made all the plans so I'm sorry but it's obvi his fault I don't care what anyone says it's been proven time and time again and my dad agreed and told me even he was upset he was not invited as well 😏😒...  my father then said I want to take Jared my fiancé out to lunch tomorrow I think it's prob to talk to him about it... he doesn't have to but I said ok... I now text my coworker/friend because I'm not just gonna let her get away with thinking I believed her lie... I told her that i knew it was all planned by Joey and another friend and I said listen if you lied to me because you were told to not say anything I'm not mad at you but at least own up to it.. she swears she knew nothing then admits she knew that her bf my cousin booked the rooms but doesn't believe he didn't invite my fiancé and swears she stayed out of it ... what the hell was I supposed to say though honestly I think she knew everything because everything just adds up to that and I'm mad at her for making me believe it was my bros fault also... she tried to them twist her story saying she never says it was him she said thought maybe he made the list of ppl invited .. it's just like honestly shut up .. I then explained to her how there is no excuse gave her all the angles they could poss use as to why he wasn't invited and every response of how it's still fucked up.. she claims to agree with me and she said she completely understands how upset I am and that I have every right to be upset... I'm at a loss now up can't sleep and I have to go to work tomorrow and face her!!! Any advice on overall everything I've written??? Sorry so long...TIA 😏
