SC, keep the faith as long as you can. I feel the same way. Both our spouses will turn back to us...just not on our timeframe. If my W continues to move away from me, I'm going to be OK.
One of the things we need to do is become the attractive alternative. If your H notices and comes back that would be great. If he does not then you will be ready for a new relationship. That is the secret of GAL that everyone talks about. The more confident in yourself that you become, the more attractive you will be to him.
