AM I WRONG??

Ok so my boyfriend and I want to buy a house so we can live like an actual family with our daughter instead of my moms basement. Anyway so I told him today hey I’m gonna need help contacting the realtor and stuff like that he looks at me and says why? I’m buying and I said well for 1 you don’t even have enough saved and for 2 we might need a co-signer and I said I would most likely ask my mom and he said “no I rather put my sister” and I said ok, but your sister has 8 credit cards not paid off and doesn’t even have her own house. My mom is more dependable (I think) anyway he goes to say OH so then when you’re tired of me and kick me out you’ll just say it “your house” just like your mom does with her house telling your dad that and I said HOLD UP my momma got that house BY HERSELF my dad was not around to help. He said “yeah but he’s helping her pay it off” and I said SO it’s her house PERIODT. He got upset and I’m driving and he said just drop me off here(at the corner) I wanna walk home as we were on our way to the park w/our daughter. Now. If that’s what he thought right away then why am I trying to get a house with you if that’s what you’re gonna think. Now I’m second guessing MAYBE I SHOULDNT. Idk. He still had the audacity to text me and say “I’m gonna pack my stuff since I don’t feel welcomed here” like wtf? A whole ass year later and your don’t feel welcomed. Cmon guy. Anywayyy I still went to the park without him but as I got home he didn’t wanna talk and he always try’s to blow things off without talking about it. Or like it never happened. Idk. Maybe I’m not even happy with him anymore but that’s a whole different story. But am I wrong??
