While divorce 2.5 years we got back together & it isn't working out, we combined income stopped child support. Do i still give her half again?

Do i have to give my ex wife more property if we got together after being divorced but living together. My wife and i divorce about 4.5 years ago at the time, I had cheated and felt very guilty and confessed to her she was very angry, but didn't kick me out. ......Until she finished her education and then she asked for a divorce. I gave her everything, the house more than expected child support and took on the debt we had. We are not rich or even middle class. She quickly moved on and found some else several someone elses. Then I found someone that I thought could share my life with. She asked me to think about it because she still cared about me. I bought a house and stayed with my new partner. Then our daughter got sick and we got back together. now two years later, she has moved up in her job and thinks her job is more important than mine(i still make more money) she feels she needs her space. So, she goes out almost evey Saturday, with her friends and most times does not get in til 3:30 - 400 . We work opposit shift so we pass each other during the day. I have Wednesdays off and she decides to going to an unofficial weight lost get together on Wednesdays. Some times we go days without talking. This Weekend it came to a head she went out on Saturday I work so my parents to the children to a party. On Sunday, my mother was going to stay the night because we were going bowling and it would be late night. At the last minute she calls my mother and say that our daughter is sick and she isn't feeling good herself, so not to come. I decided to go to the league. After bowling I stayed talking to some mutual friends and lost track of time. I didn't get home until 3:30. She had taken our children to her parents while I was out and told them I was sick and if they the children spend the night. The next morning I had to search for my kids because she wouldn't tell me where they were. She needs her space. I have suggested on many occasions to get counseling and she won't go. I have decided to go by myself. I don't want to hurt our children, but I feel she wants a babysitter, house keeper, and cook not a husband. I lost everything the first time around will i lose it again. She sold our old house and invested some of the gain few thousand into my house? We stopped child support because we were living together......what happens now?
