Trying to get rid of him but he won't leave.

Show my husband cheated on me about a year ago since that happened trying to get rid of them. When I had my suspicions claimed he wasn't but then two weeks later he bought me a car. When I went through everything is so every bit of proof that he was cheating on me all the sudden he want to start giving me money. I found a dating profile that he claimed he never had all of a sudden he want to be a caring husband. Then he comes over II phone claim it was her business but then doesn't want to give it out to business people. So one day I look beautiful while he was sleeping and I brought inappropriate text messages to another woman marking her as his Queen. When I confronted him about it he said it was a joke. So I just connected the phone that's underneath my name that goes to him and told him that he can I have the number until he knows his stuff out and leaves. She refuses to leave we have a child together and I really hate to get police. What can a girl do?
