I agree with everyone's thoughts......she finally realized how great things were with you before and she is definately having second thoughts now.  I say it is too late.  I assume you are happy in your new relationship so concentrate on that and let the ex be jealous.....a little too late now to realize how good things were.  Funny because my husband cheated on me and then wanted a divorce.  It was very hard, but I accepted the divorce and moved full force with gaining control of my life.  I don't know if my ex ever had second thoughts or did things like you said here, but I do know he made comments months ago about how I looked so happy and "ok".  I remember saying that I was.  He did not know that I was started to date again and seeing this wonderful man at my work.  Once he learned about my boyfriend I am sure it all made sense, but it was great in the earlier months to have him wonder.  I do think about it even to this day....does he ever think twice about divorcing me?  Will he realize one day that our marriage was not that bad and if we just communicated more we could have been great again?  I guess I will never know the answer to that....and not that it matters, but the not knowing drives me insane at times!  :)

I cant believe you dont know whats going on......duh silly! This is a case of a woman who has realized just how good she had it!!! She has finally figured out that the grass is not always greener on the other side. That whatever she had going on with this other man or the next didnt compare to the love you had for her. Now she is trying to jump back in your life, by telling mutual friends she is miserable. Wow!! The nerve of some people. My thought on it will be, think long and hard on what you really want. If you are happy but feel that you could be happier reconciling this relationship with her, go for it. Be aware however that this, maybe just a little game to see if she can still get you. You know, like to feed her ego. Just be careful!!!!!!!!!!!!!!!

Thank you all for your input on the situation I am in. It makes me feel good to know that I am doing the right thing.

Seems like you  gave her a chance. Now she is seeing that the grass is not always greener on the other side. I would move on with my life.

I have to agree with everyone hear.  The affair is not as exciting when there isn't someone there too cheat on.  She's trying to control and manipulate you.  If she was really willing to reconcile it has to be on your terms completely.  First figure out if its something you want, not that you are just being nice and its easy.  Figure out what you want, what it looks like, and what it will take.  You are in control not her.
