Am I the problem or these weren’t real.?

I was 16 when it started with 1 guy he was 27 but then he left & someone else who was 26 came along now I’m 19 with his baby. He says nobody will wanna deal with me cuz I like to “argue” (I just be saying how I feel n he takes it as I wanna argue). Anyway I can’t help but to feel sad especially when I see people my age married w kids or just in a happy relationship I just don’t understand why I couldn’t have that or at least be like that with someone I have a child with.. Or he just says nobody will want me they’ll just wanna have sex & that’s it. So I asked him is that all you want since you keep saying it?..

I’ve already finished school I graduated June 6th🙂.
