I have been going through similar issues. My marriage ended last August. I'm not sad it ended. I'm sad that I don't have somebody with me anymore. Codependency. I was dating a guy last fall, but it wasn't serious. Then in Jan. I met someone & we became serious in March. We just broke up yesterday. He was a player & I didn't want to admit it. The first red flag was when he went to a friends' birthday party & brought his ex-girlfriend/friend of 16 years to the party & I was at his house. He didn't come home til the next morning at 8:30. The night before I found a planner while looking for a notebook. In there was things written down where he was, who was visiting or he was visiting, when he had his son, etc. There was a weekend in April where he had written down on Friday night, Jaclyn (a friend of his from college) and Saturday night, Chandra (a girl he met on POF like me). He lied to me about that weekend. He told me he was visiting a friend of his in a different town. I confronted him the next day. I asked how he felt about me. He said, "we mesh well together." Not I like you, I think you're pretty or beautiful but mesh well together. Which I have to agree we did get along very well. When I asked him about the planner, he said that I had issues with her that's why he didn't tell me. I was more upset with the fact that he lied than the fact that he went to visit her. 2-3 weeks prior to him visiting her, he was with me & a friend of mine at a bar. He texted Chandra where he was, about 6 miles from her town. Why would he do that? Because he was playing me. He told her he was staying at a friends' house for the weekend, not his girlfriends' house. He also never told his ex-girlfriend/friend of 16 years about me. It hurts to know that he was with me only for sex & never told me how he felt. I told him all the time that I liked him. Now, I'm back to square one. Struggling with the self-esteem, depression & loneliness.
