how to deal with an angry ex-husband?

[peaceSJ]

Three years ago my husband met his ex-girl friend and fell into love with her again. Since then he was so easily to get angry on me, and blamed any of his unsatified or unhappy things on me. We got divorced lately, but still have to communicate with each other because we have two young kids. We share the custody. However, My husband was very uncooperative, and always yelled at me for no reason, even in front of the kids. It seems like any single word I said and anything I did was wrong. I was abused by him. We've been married for more than 15 years with two lovely kids, I just couldn't understand how come a person can change to such a selfish and cold-heart person. He treated me as his enemy.

I am here to ask for your help. How can I stop him abusing me?

Thank you,
