You'll move on and work on yourself in all due time.
In the meantime, trying to figure things out is a part of the moving on process. There may be much you don't know, but as you work through it all, I think things will become a lot clearer. Red flags you didn't see at the time appear in your vision again. Words you believed back then suddenly sound like horse-pucky. The further you get, the easier it is to let go of the denial and face it for what it really was.
Go easy on yourself. Its normal and natural to grieve the loss of relationships, even if we know its best to be shed of them!
