Was just skimming through your posts. I love your attitude. It's one I try to hold on to everyday. I have had the same conversations with my H. You are a little further along though. I have told H that if/when we separate it will be his decision and that we would have to put some distance between us friendship wise. I told him I would need space to let him go. No casual lunches to just hang out, no going to the store together etc. I did tell him that we can get together for and with the kids.
This scared the life out of him. H honestly thought we could remain best friends if our marriage ended. He keeps telling me I am and have been his biggest supporter, have encouraged him in ways no one has ever done (his family was pretty much hands off while he was growing up. His parents are divorced and both remarried)
I think you are going about your sitch in a positive manner that will come around and reward you in the end. I am a total believer in Karma...
