As long as you're being sincere about all that and you're not just trying to fool yourself and you have actually dealt with all the emotions you needed to in order to get over the break up and grieved and forgave and made peace with it, then you are in a great place right now. You're happy. Happiness is light, it's the ability to just find joy through tiny things because you're good. If you're being straight with yourself though. Sometimes we have those moments of sadness and of pain and the memories flood back, but that's OK and it's normal and you've dealt with it in the best way possible. One day, you're not going to be even interested in looking at her pictures and that will probably be the day she waltzes back into your life with a 'hi'. That day when you don't even feel that little pain is the day she will most likely just turn up out of the blue and you'll look at her with either confusion because you forgot how you used to feel about her and you don't really know what to do with her or you'll look at her and think, ok yeah let's go, I still think you're cool. But you won't be in a rush and you won't be insecure or having mini heart attacks, it'll just be easy. It's happened to me and it happened just like that, no big fanfare, no big heart attack when I got the message, just a feeling of 'ok yeah, this is cool, I'm ok with this' and I went super slow and built it up and then after a little while, I got those feelings back. But he came back when I didn't have super strong feelings, when I wasn't even checking his facebook anymore or cared much when I heard his name. I was too happy with my other stuff to care.
