Feeling hopeless

Whenever I ask my husband to look after my child or interact more with her he told me I was the one who wanted to have children so I need to be responsible to take care.he will do his part that was agreed upon. I feel hopeless how can someone be so heartless and say this kind of thing like the child is only mine.i wonder why then the child has to take the father's surname. Maybe I should change to my surname. Maybe I should consider divorce.
