am I crazy

I can not tell anymore. My ExN is playing all these games. telling his brother he wants me back and in the same sentance tells him he is living with the OW. Then he sees me and game is on. Just found out from a friend that he posted pictures of him & the new woman on FB. I didn't see the pictures or ask. But all the same now I am furious!!!

I am so angry. because I feel like I am crazy. I know what and who he is. I know it is all fake and an illussion. His new GF is not even on FB so why the pics?

Am I crazy to think it is all to get back to me through mutual friends? Or is he just living his life and moving on and this really has nothing to do against me?

Please help I am confussed.
