Ex husband

Sarah
My husband and i split up at the end of June and we decided to work it out then he stopped talking to me altogether.. Well the end of August he came back and we had sex. Then we were going to work it out again. Well I had found out he was sharing his time with me and another woman he had met off POF... We've been having sex ever since and I fee like I'm sling something wrong. Should I leave him alone or continue to work it out with someone who doesn't think I'm a priority and gives me mixed signals...?
