Tired everyday but husband don't appreciate!

My husband show me bad attitude ever since I given birth. I work, I take care of baby, I do housework, I make milk and feed baby in the midnight, yet when come to any disagreement he will shout and lose temper to me. I feel disappointed. I dun deserve it. My baby is Singaporean but I am SPR. When come to divorce, I want my baby to be with me because I think he is not able to look after baby, but will my citizenship affect anything?
