Attaching to the new thread. I like this thread, I feel there's somewhere I can go to read about LBSs with Hs like mine. My H was boomerang, then clinger, then vanisher. If it weren't for my S13, I think I'd never see him.
I think vanishers/or what we have, feel so bad when they see us, that they have decided the only way for them to feel ok is to avoid us. I think what Rising Phoenix said about her dad is probably how most of our vanishers feel. They don't have the strength or courage to try to go back to the wife, or to get out of the OW relationship. Maybe our vanishers are weaker than the clingers, or more proud than the clingers, or don't seem to be able to swallow their pride enough to do something to fix the mess. It's as if they tell themselves there's no hope and that's that.
If only, I don't see any harm in sending your H a regular update, maybe once a month and not every day. He said he enjoys your friendship. I think just like others have said, that while the OW is around, they are going to avoid us and the kids. They need the OW and the OW has given them an ultimatum: no contact with us at all of any kind or they will dump them. That's terrifying to our Hs now.
If we can maybe just accept this fact. If Only, your H was quite open about his situation with you, and thanks for sharing it with us. It gives us an insight into many of our Hs. While our Hs are in the throws of the OW, they are turned away from us, even though they might not want to be. There is no point expecting them to interact with us or to have some miracle awakening when they read a message from us. It's not going to happen that way.
However, I do believe, that when our Hs are fighting with the OW, or have broken off temporarily with the OW, and we happen to reach out in that moment, they can turn back to us. I don't mean as in reconnecting or anything like that, but maybe a touch and go, or just a good feeling about us that is a seed they store away.
With vanishers it's very hard to know when they are fighting with the OW, so If Only, if you keep the line of communication open, you might catch one of those moments. I think the secret is to send your messages without expecting them to get a result. No Expectations just described MLC on her new thread as the movement of a frozen slug. I really believe a nice message/email with no pressure attached is a healthy seed. So if you want to message your H then do it. But not every day. I really think the MLCer needs space to work through this crisis.
