i regret marrying my husband

i hate my husband. he has debts he incurred when he was still single. i only learned of them when we had a child and he cannot settle the monthly dues anymore. i had to loan some amount to help him. i cannot resign from work because he cannot provide for us alone. my baby is being taken cared of by my sister. we only spend time with her on weekends. it pains me that the person i married is not able to fulfill his responsibilities and is even the reason why we're not living comfortably & why i had to ask my sister to take care of my baby.
