Hi Tumbling, my impression is that it's a part of your character to rather act than react. The standard DB approach is to be on the dim side but looking at your situation, with a very passive H, in order to keep any communication going it's ok to text him occasionally by yourself, let's say 1-2 times a week. Don't expect anything, just write if you feel it's something worth telling him. Don't necessarily inform him of your GAL activities, these are primarily FOR YOURSELF.
on the other hand a man has left his wife and she may be done before he leaves the tunnel
Eventually that would be ok, too. You have every right to move on, standing tall. I haven't investigated your threads - have you ever wished to have children?
