Relationship gone wrong

Ok so here's the thing I've been with my husband of a year for seven years now and a year and a half ago we really wanted a baby we tried for months and got married Everything was good then 4 months into being married he cheated on me with 3 different people two of which came from a different state and payed for a hotel after being confronted he had promised he would change and straighten up only to get caught two months later talking to other women in a way he shouldn't have been I became distant ready to walk away from 6 1/2 year relationship he begged me to stay and I did with all the above being said it's only been about 5 months and all thoughts of having another kid are out of the question but it's making my husband mad he thinks everything is ok and that we should be the ones having a baby not my sister in law who he's been treating her and my brother differntly she is currently around 5 months pregnant and he treates her very rudely at times and I have a feeling it's jealouscy I can't even get him to help me take our dogs out lately how could I expect him to help with a baby I've had the thought of leaving him but I can't afford to do that nor can I get past the fear of accatually doing it he's been making rude coments and called myself and my daughter stupid asses right in front of her shes 6 she understands what he says has anyone been in a relationship like mine if so what did you do I'm losing my mind always mad or depressed
