Psychfan123,
What he did to you really stinks. He is soooo immature in his behavior and probably will never grow up. Ha! He said he "wasn't feeling it and you were too different". That is the lamest excuse ever. I just think he is like a little boy and found some new candy to try out. The fact that he refuses to take accountability for his actions also indicates a lack of maturity.

I'm so sorry for you, believe me. I am going through something similar myself. His link with her over sports is superficial. He was just looking for an excuse to support the real reason why he dumped you, which is most likely, because he wanted to change the flavor of his candy. I wouldn't say that she is more suitable for him than you. Actually, I think you hit the nail on the head when you asked "Is he just idealizing the beginning of the relationship and destined to do the same to her?" The answer is a resounding YES!! I have no doubt he will repeat his same behavior with her. Having sports in common is by no means a glue that will hold them together. Whatever drew him to her initially will fade over time. His infatuation with her is temporary. Guaranteed. It's so sad for you (and me) to have to watch it unfold.

As for something to think of when you see him at work, I would think about the fact that he is repeating with her, exactly what he did to you. He will wind up hurting her the same as he did you. I feel bad for the nice young lady that my ex is currently with because he will be hurting her just as badly as I am hurting now. I also feel a little sorry for my ex because he gave up a good thing with me. I think yours did too. He may walk around like he's on top of the world now, but it will not be for long. The poor girl he's with will eventually find him cheating on her down the road. That's the kind of man you had. He's lost and doesn't know a good thing when it's staring him in the face. He may be sorry one day but he may not. He may never wake up to his own obsession with needing different women to love him. I'm just sorry you and I have to suffer at the hands of this low life. I am angry too and don't have any suggestions on how to deal with it or on changing how you feel about him. He didn't deserve your love, that's true. People tell me that too but it doesn't help the pain. My heart is broken just like yours.
