My ex and I were off and on for almost 3 years. For almost a year, he started talking to a girl out in California. When we got back together, they stopped talking. He moved out to Las Vegas to be with family and we broke up, but talked everyday. I officially ended things when I found out she came to visit him. They then went into a relationship. He would contact me by email and text, but I'd ignore him, but somehow I gave in and we started talking again. He came home to visit and I went to visit him. He ended up cheating on his girlfriend with me. He moved out to California to live with the girlfriend for the summer. He calls everyday and/or texts when he isn't with her. She went through his phone and found the text messages from our conversations and broke up with him. I don't know what to feel or think right now. He's my best friend and I'm still very much in love with him, but confused. Help?
