Depressed

I moved out at age 18 with my now fiancé due to my mom getting married again and treating really bad. Her husband has completely brain washed her we use to have a close relationship talk about anything to her just bashing me every chance she gets. She even talks about her step kids and how much she has respect for them and loves them& there all adults. I don’t work because my fiancé thinks I should stay home take care of the house & take care of the kids and if i get something new she accuses me of selling drugs. My fiancé works really hard everyday and it pisses me off that she would even think that of me which I really think it’s her husband putting things into her head. Monday we got our new place and as much I would like to tell her about it I feel like I just can’t, she looks at me with disgust and says she doesn’t respect me no matter how hard I try things will never be same ...
