Will this situation become more than what it is or is there no future

This a fwb situation:

Almost 3 years ago i met this guy. Really didn’t like him. Eventually 3 months into the friendship we messed around. He told me he wasn’t ready for anything serious and i agreed. Wasn’t looking for anything neither. Months went by (I’ll admit i had blinders on during this time) we spent time, got close, met friends and family and children, and boom. The end of last year i get pregnant. He wanted an abortion i wanted to see if i was going to even carry it (history of miscarriage). We fought and after the miscarriage, he walked away (power struggle). Weeks went by we didnt speak (2 to be exact) and we argued and talked here and there and ended up messing around. He was angry but wanted to try to fix our mess. Christmas i had a talk with his teenage daughter, and she told me some information about the pregnancy and the abortion situation (why i said something idk). To avoid getting in trouble, she told her mom and dad i told her everything and he believed her instead of me (his hangups more to it, but for another time). We mutually agree to leave each other alone, but he comes back, also says i can’t see the kids (truly hurts but these are his kids). He starts to come around more, and still says he doesn’t want a relationship. I’m on my idc vibe and we still mess around. Recently i asked him does he see a future with me and he said yes, and i took it for face value, but on Friday (my birthday) i decided to get clarity. He refused to give me anything but keeps saying I’m the only one he’s seeing. When i told him to just be honest and tell me if he doesn’t like me and this is a hook up he gets frustrated and say why does it matter? He looked in my eyes and it seemed like he seen me turn cold that day, and when i left, his smile dropped into a sad face for some reason. He’s been reaching out but right now, I’ve just stooped talking to him altogether. He’s in the process of getting me a car and some other stuff, but I don’t have the time anymore to be dealing with a wishy washy person while I’m trying to better myself.
There is a burning question and that is if he will ever change his mind and decide to pursue me or if that is a lost cause. Any feedback will be appreciated ( i just turned 34 if that helps)
