Not happy anymore

Anybody else not happy with there SO anymore?? We had our baby on the 16th and ever since then we don’t say I love you or even kiss eashother good bye. Also I’m with the baby all day & he watches her for a couple hours at night and he acts like he does everything. Yes he is working but he still gets at least 10-12 hours of sleep. When I get maybe 5. He also says stupid little comments to me that just infuriate me. I’ve talked to my parents and they have already told me I can back home with the baby and they will take care of us. I also will tell my SO I’m going to leave and he tells me to go As long as he can see the baby. Then he made the comment the other day during one of our arguments he said that he will come and see the baby when she’s 3 and a little older so he doesn’t have to deal with the crying so much. Also he went to the movies on Monday with his brothers when I’ve been asking him for a little break for days. I really needed to vent this out I’m sorry

UPDATE: he has epilepsy and isn’t isn’t suppose to drink because then he can’t take his medicine. Last week he had 7 seizures and today he went drinking with his brothers. I think tonight was the final straw.
