Just wanna get a few things off my chest

First off pregnancy hormones please stop making every little thing bother me and maybe I’ll be able to deal with problems a little better 😂🙄. Okay but other than that I wanna say I really wanna talk to my roommate about the way she’s been acting since last night and maybe the past few days, we’ll last night was kinda the start to everything that happened today. So last night something I shouldn’t of even have to do at 11:30 while my fiancé and the other roommate we have were sleeping she decided to come in with one of her friends and be loud as ever after complaining about the roommates who live in my basement being loud when they haven’t been loud since my fiancé told them off about hearing their tv and music 2 floors up and haven’t had a problem with them since, but let me get back to the point I had to tell her to be quiet when it should’ve been common sense since all the lights were out no one was awake when she walked in but it’s fine that problem was solved they were quiet and everything, so fast forward to this morning I walk out of my room and to her friend dying her hair in my bathroom like hold up shouldn’t you ask before you just go into someone else’s bathroom and start doing shit like it’s been recently redone the tiles the sink the vanity the medicine cabinet and the toilet like I’m not even allowed to do my hair in there I do it in my bedroom and this isn’t even my rule my fiancé made it since I did make a mess once dying my hair and got a stain on the old toilet and all I tell her is you can’t do that in there you have to do it in the room, and I walk back into my room and not even 5 minutes later all I hear is bitching about being told about how you can’t do something somewhere like there’s 2 of you do each other’s hair it’s not that hard, and seriously if you have a problem with the fact that I said you can’t do you hair in the bathroom why didn’t you come say something to me or ask me why instead of bitch about it I would’ve explained it to you I didn’t have a problem telling you why. I don’t understand what her problem is like if she has questions or a problem with the rules why can’t she come say something to me so I guess when my fiancé comes home we’re gonna have to sit down and have a talk with her or something since all these problems just recently started. And not to add to the fact that her friend just walked into my house with out knocking or anything 10 minutes after she walked in like no I just wanna put that she’s lucky my dog is a horrible guard dog and is meant to cuddle and give love and that’s a true story but a story for a different time. But I just wanted to get that off my chest since I can’t say anything to someone with out them having a problem which sucks since im trying to not let my hormones take over and have me flip out which I feel like I could but I wanna be nice and someone please tell me that it gets easier to control as my pregnancy goes on since I don’t wanna flip on someone for something small as someone bitching about me telling them about the rules, I hope it does but than again sometimes it’s needed in certain cases but this one I felt it’s not.
