is it the hormones ? feel no connection with my husband

hi all, i’m writing this because i need to vent and i feel i have nobody to talk to about this ... i just had a beautiful baby girl 3 weeks ago. she was born at 30 weeks so she is a premature, but thank God she is doing great! :) .. my water broke at 30 weeks in which i had to stay in the hospital. in those two weeks my husband was very attentive and took care of me as he should have .. however, after the baby was born i feel like our dynamic has change for the worse. right now anything sets him off and annoys him ... i’m very sensitive and it has affect me to the point that i told him i can’t be around him, is nothing that he says is more his energy and no affection.. right now my life consist in go to the hospital to see the baby, come back home to eat and rest and go back again to the hospital; my husband is also home ( he took time off) but he stays home in the morning, wakes up and expects me to cook for him, serve his food when i get home from the hospital and we go together to see he baby in the afternoon.. i feel this is soo unfair of his part, sooo selfish! i have not mention anything to him, but is eating me alive how can’t he see how selfish he is!!! .... you might wonder why i have not said anything? well because his actitud has shift and when i have talked about anything his looks at me like I have 3 heads.. the only thing he had said is that because i’m sensitive he is giving me my space .. but if that’s what it is, it had made it worse, don’t feel the love or the caring from him and i can’t talk to him about it
