Sahm problems smh

So I stay home with my son. He’s under 1. I’m still struggling with my weight at this time. However it’s slowly going down. But I’m still wearing my maternity underwear and some clothes because my regular clothes won’t even fit me yet. Not sure they ever will. Anyways I stay home and his dad goes to work. And normally he doesn’t have an issue buying me things however he says he won’t buy me any new clothes. He’s tired of spending money on me. Apparently im a huge inconvenience to him. Yet he stays with me for what reason im not sure. He doesn’t like me. Tbh, it’s hard work being in a relationship where someone doesn’t like you. It’s easier to break up. And I know what your thinking im making excuses, or I can just leave. Well I can’t. I’m one broke person by myself. Idk I feel trapped man. He doesn’t want me to look good or anything. Meanwhile he’s out buying naked feeling boxers at like $25 a pair. I just don’t understand how it went from men complaining about women buying nice panties from like Victoria secrets like 5 for $22 or whatever. I just don’t get it. Probably never will.
