So it's been about a month now since I broke up with my ex and I feel a lot better now and I feel like I'm making good progress in getting over her, I feel like the healing process is coming to an end. Whenever I think about her, I just remember how mean she was and how she manipulated me and I feel a lot better knowing that the relationship is over. I haven't talked to her since we broke up and from what I've heard, she misses me, but I don't think she misses the relationship. I have been friends with this other girl for about 6 months now and we watched have been spending a lot of time together since I broke up and she told me she really likes me. I told her the same but also told her I'm not comletly ready to get back into a relationship. She is extremely funny, goofy, smart, beautiful, and is just a great person. She complely understood, and I have this weird feeling that something is holding me back.I think what's holding me back is that I don't want to upset my ex when she hears I have found someoneelse and I feel like she'll think badly of me that I like someone else already.I think I feel this way because I still care about her and I don't want her to feel hurt, but I know I don't have feelings for her anymore. Why do I care what she thinks and why does it make me feel this way? How long should I wait to get back in a relationship?
P.S. This new girl is not a "rebound girlfriend". She is deffeinetly an improvement from the last as this new girl is much more emotionally stable and we have much more in common.

Let me tell you my story first. A few months ago I had a BAD argument with my husband, the worst we've ever had over the 7 years of our relationship. I was sure it was over and I hated him, I wanted out of the marriage and for him to be out of my life. But I had a dream that he got a new girlfrind and I was horrified, I woke up in cold sweat and was so relieved it was only a dream. And I thought to myself, how come that in the daytime I hate him, I can't bear looking at him and yet I was so upset to imagine him with another woman. So I guess what happened to me and to you is that that person (my husband and your ex girlfriend) has left a trace in your heart and she will be there for a long time, maybe forever. You may fall in love with another person but your ex will still be someone close to you even if you don't quite realise it. If you have made up your mind and you are sure you are never going back to your ex, do what you feel is right - if you really like this new girl and it is mutual, start a new relationship because if you don't stop looking back at your ex, your new possible relationship may never happen if you wait too long. And ask yourself - would my ex care how I feel, especially if she never did?
