help with problems

I am a mother of 5 and me and my husband have been separated for 2 years we recently started back talking and decided to move in together for the kids sake. I am still wanting the divorce because I know that he has dated alot of woman in the 2 years I have been gone. recently i found some evidence that he has been with someone recently and he has lied to me on numerous occasions about where he was going. I have brought it to his attention and he said he didnt know how i would react to te situation and that he doesnt know where him and this girl is going with what they have. I am so angry at the fact that he lied and I need some prayer because I have sacrificed so much for my children in the past 2 years and he hasnt helped me at all. I was under the impression that he wanted to work things out but I guess I was wrong now i am hurt and dont know what to do. I am so tired of being hurt by family and him that I have been thinkin bout doing things that are wrong. I dont like to feel this way please pray my strength to get thru this I just dont think I can go on like this anymore. I really dont want a divorce but theres nothing left to be said or done but to end it. just pray for me that god show me the way he wants me to go because I am a lost sheep right now and cant find my way.
