Bea, I'm glad you returned to post a bit. I hope that you've been enjoying some peace and quiet over the summer. How's the gardening going? I hope that you and your family are doing well.
Your xh sounds like he's finally settling down just a wee bit and has come to realize all that he's lost. Some do the necessary, hard work and others don't. Those that don't are the ones that may stumble along in life and never be truly happy.
Bea, you gave the situation your best shot. You did everything you could and it came down to the fact that it was all about him. You, your children and the relationship were not the problem. We walk the path for many years, thinking that we may have triggered the crisis or if we had done something differently, etc., but when we do finally cross over to another path, step back and finally look back, we come to realize it's not about anything we could have done differently to prevent it. The crisis was going to come sooner or later and something in the universe triggers it for them.
Bea, your xh lost a wonderful, kind, compassionate and intelligent woman. He is slowly becoming aware of what he's lost.
Take care.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
