His criticism seems to be having a toll on your self esteem and how you feel about things. Maybe this is the "change" your talking about.

I can't give much advice because I live through something similar and put up with it. I've actually put a brick wall to his words and no longer even hear them. But I've been doing this since I was 16...2001.

All I can say is if you aren't obligated to this man and want more then you should leave him and get more...for yourself. Easier said then done...I know

Good luck hun
