Its hard to live with a stepparent that hates your husband

My stepmom really hates my husband, im just glad my dad likes my husband. I always remember what my dad says every time my stepmom points out how much of a loser he is. She hates most men she thinks anyone who isnt rich is a loser. My husband works hard hes going to college. His main flaw is he is not good with money he spends it on insignificant things. Im trying to work with him on that but i just dont know what else to do poverty mindset is strong its mainly that hes wasteful. I scheduled an appointment with a financial advisor but that did help and the bank and my social worker. Sometimes i wonder if i wouldnt have gotten accidentally pregnant if i would be still with him. But i dont want to break up my family. He uses his childhood or his age as an excuse and he thinks our marriage is good. And he sees no issues. Hes not that young anymore he was born in 2000 and ok im older i know better but i cant wait for him to mature we have a son whos going to suffer from it. He blames the economy he says i dont understand because i dont work, but i also dont spend any money.
