Hello there David. Nice to “meet you” and I would very much like to help you out. I too just like you was in the same emotional state, but guess what I’m free and clear today. It was not easy, but I pulled through. For me the last straw was after all the back and forth, restablishing contact and experiencing the dreaded silent treatment followed by an excuse after I tried to be real and vulnerable. That was the catalyst. In the months that followed, I got back and “focused” on my career while at the same time trying to heal myself. One tool that I used was on YouTube and watching videos from Robert Wong’s Self Redirection channel. It really did help. Learning that others behavior are not your responsibility and that they are just hurting, sometimes even worse than you are. Improve your self control/ discipline by blocking her out of your life; real and social and start healing yourself. It can truly be accomplished. Thanks and take care.
