Gosh, G...sounds like my prize-winning XH has gotten a divorce from his latest tart and you have found him. LOL Just kidding, but I'm not far off. My XH is a gaming addict and is ALWAYS on his phone or Ipad...or at least was when we were married and by all accounts still is. I just don't have to deal with it anymore. Not my circus, not my monkeys. LOL
I don't blame you for hanging in there. I have a hard time stepping back too. And, it gave you some company during a stressful time, so that can't be all bad. Do what you need to do.
As for your XH....well, bless his heart...................
