Tired of hearing ex name . (kinda long please read)

So my bf has a ex who was before me they’ve been together for 3 years & we all went to hs together we recently graduated I’m 18 & he’s 19 . I would hear about this girl every single day & it was so annoying . In the beginning they would still text a little and she would tell him her issues that were going on at home he didn’t really care or pay much attention to her but he never told me they were texting either until I seen her name pop up in his phone while he was showing me a video. I got upset ofc and he grabbed me telling me how he doesn’t want her she just blows him up blah blah (like blocking people doesn’t exist) they lost their virginities to each other and shit so I guess 🙄 but he had been single for about 9 months she had a bf and wanted him back it was a mess a whole bunch of chaos . She cried on his stairs begging him and just doing the most . He told her he has a girl (me) and no he doesn’t want her and he was just like don’t u have a bf like wtf. Anyway her bf fought him because he thought he was the one trying to go after the ex again until he posted their messages showing his ex trying to get back w him and they broke up blah blah & I was just here like

Minding my business. I was going to stop tlking to him just because it was way too much drama. After a while everything died down I met his family he met mine but his ex’s name would still pop up he would say stuff like even (his ex’s name) wouldn’t get mad at me for stuff like this (he wanted a female to come over his house past 10pm to twist his hair) u got me fucked up. Then he would say I’ll get over u just like I did with my ex (during arguments) or he would just bring up old shit involving her and I’d be like omg nexttt . Anyways we were otp and his mom said you didn’t use to tlk to ur ex the way you did with (and said my name) cause he called me a bitch before & I told his mother lol but at first I didn’t hear her cause she always talking shit then I heard him say mom do you want me to get in a argument and she said Oh no no I don’t so I asked what was said and he told me and I was just like that’s embarrassing he disrespects me & this girls name will never go tf away I hear it from him & now even his mama wanna make comparisons . Then he said I never talk about her what are u tlking abt and I told him he’s full of shit and sent his ass screenshots of him mentioning her name MULTIPLE TIMES trying to compare how she dealt w him w how I do (I don’t take NO bs) and then he wanna act like booboo the fool all confused and shit then say Ok I used her as a example wow you’re so extra and childish you need to grow up & he also tried to flip the script on me saying how I denied talking to these 2 guys which was when I was a fucking junior and I didn’t even know him at the time & I didn’t deny it I said I was entertaining them because I didn’t want a relationship with either we were just having conversations like wtf . Then he wants to say those screenshots are old (they were on Thursday or Friday) so I said me dealing w those guys are old too so what’s the difference 🤔 . I asked him if it was me doing all this talking would it be Ok and he said it’s not wrong so I said alright ima pull a you on you tlk abt my ex and use examples of past relations and do the same thing basically. then he wants to call me spiteful and say he can do it worse .. but baby I thought what u were doing is Okay?? 🤔🤔🤔now if I do it’s spiteful and all this extra shit paleaseeeee child ! And plus his mama got no damn respect I always go over to their house she met my parents as well she knew I was on the phone!! So idk why she would even open her mouth to bring up the ex knowing all the shit she done to her son. She got him jumped & suspended as well he couldn’t participate in prom or anything. Am I over exaggerating or what I don’t see It .
