Am I doing something wrong?

[Amaury]

So we had a great relationship we broke up on good terms it wasn't ugly. We remained some what friends since we worked togther her(not anymore she left over a month ago and we broke almost 3 months ago). Then I found out from her that she was sleeping around with a few guys so soon in a short span (IMO) and I couldn't stand the sight of her or sound pretty much her very existence annoyed me and I went full NC.

 

Before I go on I just want to say the break up wasn't what hurt it was the fact that she slept with a FEW dudes so soon its as if she never cared about what we had and that's all she wanted to do all along, if she would've met a guy and started dating or became serious I wouldn't mind, yea it would've been weird but I understand that if you love someone you have to let them go and if they love you they will return, because I'm still really close with 2 of my ex gfs and I've even hung out with them and their current/ex bfs, of course I'm not close with all my Ex's but the long term ones yes because I feel like we really were friends just not meant to be together forever. Yet my most recent ex was my longest relationship, the irony.

 

Its been almost 2 months pretty much a week after I found out the news. She txted me the day she quit but the convo was literally her:"I quit yesterday" me:"congratulations" her:"how have you been? " me:"good, and you?" Her:"chilling killing" me:"lol ok" her:"mmmhmmm" I dent really consider that breaking NC but to some it might so idk.

 

Anyway the point I'm trying to make is that I have excepted the fact that we won't ever get back together again and I don't want to, I don't like her as a person for being such a cool person for almost 2 yrs to completely doing a 180 and having no respect for herself or me. I started forgetting about her more and more and I found myself actually being happy and having girls talk to me more.

 

Then recently I'd say a week ago maybe less I was having a dream that had nothing to do with her and she pops up out of no where and tells me that she has a new iphone, we were always android but honestly who cares right lol? Thats literally all that happened and the dream continued without her. After that I have found myself thinking about her more and more and it gets me mad because after all this progress why is this happening now, I want to stay happy and keep improving but I slowly feel myself getting into a slump again. Was I in denial this whole time? Plus I'm getting mad at myself for thinking about someone like her and its leading to more negativity. Any advice or has this happened to some else where you start getting over someone you used to love but stopped and realised you don't want them anymore but you start thinking about them again?
