My man cheated me

I found out my man had many relationships with other girls and even date to province while I was pregnant my last son. I found out that it was already two years that he cheated. When I first time found out he said he would stop doing that. Then I found out he did not stop. Then this time he promised to stop. I have two kids and I am so stress out and always doubt for what he is doing now. Cannot accept love from him but parents does not allow me to divorce
