Im so confused and tired! advise please?

ive been in a relationship for almost 4years with a guy we had a baby 2years ago and got married last year. my husband can be so demanding and always wants to be right for everything im tired of always bending my arm for him i do everything i can to make him happy sometimes i just do things just to see him happy to. he is always concern about bills money and mostly himself at times! i do tell him these things but he gets mad when i tell him how i feel! im always apology zing all the time for stupid things im tired of being used im tired of feeling sad and crying over him why!
