relationship talk

so i’m 23 soon to be 24 a year ago on October 2020 i started talking to a guy i known about him for years but when he graduated he had a gf which i knew as well, well we all went to high school together but we never talked to each other it was a very small school so everyone knew everyone. First time i saw him was when i was planning on skipping with a friend and we bumped into each other and thought he was cute turns out my friend knew him because his sister lived with my friend and she gave me his instagram but like i said we never talked and i forgot he even existed tbh this was back in 2013 so anyways fast forward everyone knew him and this girl dated then they graduated in 2015 and since i had him on instagram he would post her then later on had a baby with her in 2016 after that i guess he just went ghost on social media and never posted and i forgot about him i went with my life then on 2019 i made a new Fb because mine got deleted but i wasn’t really active til 2020 when covid got around and i was always home due to everything happening and i noticed how he always was reacting to my post but nothing serious he would post on instagram once in a while so i had a feeling he was single no longer with the mother of his child and he got way cuter. i had this friend i would talk to everyday since we didn’t have jobs anymore fue to covid laying us off and i would tell her like damn i think this guy is really cute but i know a bit back story he has a kid and my friend knew i didn’t talk to guys with kids but i guess i had a little crush on him then on fb he always was reacting to my post and i think once on instagram he send me heart eyes. so in October he finally send me a message and thats when we started texting everyday and he told me that he was a single father that his kid had been living with him for the past 2 years and that the mother of his daughter was not really in the picture only when she wanted too and his daughter was 4 at the time so i made an exemption only because the girl was old enough. 3 months after talking we started dating and i met his daughter me and her grew a bond til the point she always wanted to see me and always ask about me he even told me she stopped even asking about her mom, i really never liked asking about her because he always seem very stress when it came to his baby mother, he would always text her like hey when can you come bu and see her or pick her up and in the messages she would just be angry and cursing him out and make it seem like he was the bad guy but i never got in it because what if he would change the story about them or something theres always two sides of the story then my guy best friend knew i started talking to him and he was like oh seems like a great guy because he knew him from school too but my friend ended up being friends with the BM and my friend would tell me how she was always high on something or when they hung out she seem a mess mind you i had never told him about whatever my bf would tell me about her and my friend would tell me how they would hang out a lot and go to places and she would tell my bf oh i cant go see her today bc im sick when the whole time she was with mu friend and my friend would tell me like oh no shes lying she doesn’t even work on weekends or be sick because she be trying to hang out with me and she would tell my bf she was either too sick or she had work so she couldn’t go see the girl. i never told my bf because i didn’t know if it was my place to even say anything turns to find out from mu friend that she been in the mental institution twice because she has 2 types of bipolar disorder and something else my friend ended up stop talking to her because he said her life seem messy and he would tell her you need to start seeing your daughter and she would bring excuses. but anyways i loved being around both of them and got used to being around. in April when the daughter turned 5 she took the kid away from him and she TOOK EVERYTHING i guess she didn’t even have stiff for her in her own house and i went a few months without seeing her and i thought he didn’t want me around her anymore. mind you i never been with a guy with a kid so i don’t know how to do this or when to speak up about something because at the end of the day that’s not my child so we been together i guess for a year now and i had never had any contact with the mother of his child but every since his daughter moved out she goes over during the week and on weekends. this is where i dont know what to do or say so like i said he will see her 3 or 4x a week plus the weekends so from June2021-October 2021 we would have at least date night twice or once a month to have alone time then do something with his daughter. so back in october one day he picked me up early and we went to his house as we pulled up his BM was there mind you we had never had contact or seen each other, so we stared at each other and i guess she stopped bu because she had to use the restroom or the the girl did and she just stared at me and i just went inside then later on that day i guess she came back to drop off the girl and we bumped into each other in the bathroom after that i dont know but i think she doing this thing to get under my skin or i dont know but every since she seen me i noticed that she drops off his daughter every friday or saturday mornings SINCE OCTOBER AND WE’RE NOW IN JANUARY SOON TO BE FEBRUARY. i noticed this issue back in November when a week before thanksgiving she droped her off on a wednesday and she was there then the week of thanksgiving she was supposed to pick her up on black friday which she did but she knew i was there so she tried to drop her back off 4 hours later when she knew me and him had plans because we were gonna have a small date night since she agreed to drop her back off at 10pm but it was 7pm mind you the daughter was there for 9 days straight and he had her every weekend before that and he sees her 3x or 4x during the week. i would understand if he didn’t see her weekdays and he has to have her on weekdays but in his situation he has her during the weekdays and EVERY WEEKEND SINCE OCTOBER. i never thought it’ll bother me but it does because we haven’t had a date night since then and i noticed every since she saw me she’s been doing this because before she saw me she would have her one weekend then him then her like that and now her excuse is oh it’s mandatory to work on weekends but i think she’s doing it so we can stay home with the girl which i don’t mind but we dont ever get alone time since when i go during the week shes there then on weekends shes there too and he tells me he tries to do everything his bm say because if he don’t then it ends bad like it’s either her way or it’s a problem and he doesn’t like problems so i guess he’s just dealing with it but i just dont know what to do anymore because i dont think its okay and i know it’s hard but its eating me up because idk if im allowed to speak about it
