I hate my boyfriend after giving birth

I don’t know why i cannot stand him . My son is 3 weeks old and he has only helped me maybe 4 times . When he gets home from work he naps instead of asking me if i want to nap. He doesn’t help me at nights at all then claims he does to my mother. Instead of making my life easier he does things to piss me off like this morning i cannot find my keys as he took them yesterday to move my car and now he tried blaming me saying i had my keys . I cannot find them and i just started crying out frustration and anger how he does things to make my life harder . I do not feel any love for him as of right now i see his face and it just bothers me. The Things he’s doing is making me rethink our relationship . He told me yesterday “i am helping you with your son” i told him “my son?” I didn’t know i made this child all by my self?! I don’t know what to do . He pays for all of my stuff as of rn but i feel like money can only go so far i need moral support i need actual help taking care of my kids . All he cares about is sleep and he’s always “tired”
