What is really going on?
Back in 2008-2009, I started dating this girl (call her Girl A), whom I fell very much in love with & we dated for a little more than a year. She eventually broke up with me due to being a little more younger than I was. I was 24, she was 19. She was in college, I was out in the working world. She wanted to experience college. Can't say that I blame her, but it still hurt to lose her. In early 2010, I met another girl (call her Girl B), and we started hanging out. I still wasn't over my ex, and girl B had just gotten out of a 5 year relationship herself. We hung out, and started to get close and eventually dated towards the end of the summer of 2010, however, I think in the beginning of our hanging out we were just using one another as a means to get over our prior relationships. When we did date, our relationship was one sided. I found myself not giving all of myself to her, not doing nearly as much for her as I had done for Girl A, and Girl B gave a lot to me. I wasn't over Girl A and I tried to end it numerous times with Girl B, but she would get so upset and I would always tell myself, "This is a better girl for you, she's closer to your age, just give things time." Girl A was always on my mind though. I tried to avoid contact with her, and whenever I did have contact, I would get all my feelings back and wished we could be together. She never tried to break my relationship with Girl B, because she didn't want to be in a relationship. I remember one time I told her I would break up with Girl B, and she said no, I don't want to be in a relationship.
Eventually, in early January, Girl A came back into the picture, after having been gone for a little more than a year. She told me that she realized after breaking up, going through college, living life a little bit (yes, I know that implies having sex some guys, getting drunk, smoking pot, etc, I went through it too) that she was ready to settle down with me, that she had made a mistake in leaving me and realized that everything wasn't all it was cracked up to be when she was off doing her thing. To make a long story short, I did battle with my decision a little bit, I didn't want to hurt Girl B, but I knew I was always in love with Girl A. I broke things with Girl B and got back together with Girl A. Things with Girl A are really going well, and our relationship is so much stronger than it was before. She has grown, matured, is a better girlfriend than she was the previous time around. However, my question does not concern her...It actually concerns Girl B. About 6 weeks after we split, I found out that Girl B was dating someone, and I became either sad or jealous. I can't figure out whether I am really sad and kind of miss her, or if I am jealous simply because she has moved on and this is a case of, "I really don't want to be with you, but I want nobody else to have you, either." I really am happy with Girl A, as I said, but I just need to decipher what is going on in my head in regards to Girl B. I feel that if I did go back with Girl B, I would regret it in 2 weeks. If anyone can offer some insight, I'd appreciate it. Thank you in advance.
In addition, Girl B and myself have made amends, and have decided to be friends. I said I was sorry for everything and she said that she wants us to be friends because she wants me in her life in some capacity. She said she is happy where she is at in her relationship, though she does miss me at times, and wishes her current relationship, the qualities this guy has, the way I give myself to Girl A, would have been the same in our relationship. I guess he tries for her a lot, does a lot of things, which she deserves. I told her I am happy where I am at. We have made peace, and have been doing fairly decent as friends.
