Oh Sue.. I'm so sorry your H seems to just not "get it". He's SO lost I totally agree with Rob's post. Your H isn't facing reality and that reality is gonna bite when it hits him. He'll either hold on to you as much as he can, or he'll allow her to take on his responsibilities as you have all these years. Can you see this? I honestly don't think he's running to a soul mate.. he's running from the mess he's created and a new start. He just can't see he's gonna take his biggest problems with him!
Keep standing up for yourself and D4 and looking ahead. In your H's quest for freedom, fun and love he might just be guaranteeing that YOU'RE the one who'll have a chance to have that in your life. I don't think any of that's on the horizon for him and OW. HUGGGGGS! You go girl! on getting things set up for the move. I know that all of this is hard for you, but you're doing an amazing job. You're a wonderful woman Sue.. a great Mom, and although your H is blind, you've been a great W too. God does have a plan for you
