Hi Westbank,
My xabf did the same things as yours. A couple of years ago he was silent for 6 months. Then I heard from him. Don't count your silent "chickens" too early. I would have a serious plan in place for when he does contact you because in my experience it will happen at some point. I had played all the he's moved on stories in my head too.... didn't happen... he spent months drinking himself into oblivion. When he got tired of that ... he called.
