I can't believe how much your sitch has changed in such a short period of time, Regretful. I'm taking it all in. I'd better check in more frequently.
Much as I can relate to having a husband like yours and the frustration that goes with that, I can't relate to being interested in starting other relationships. It sounds like so much hard work to me. I'm amazed that you're tempted by the idea. Maybe it's because I'm nearly ten years older than you are but I really don't feel that I have the energy for a new R. Along with the potential for validation, Rs bring up so much insecurity in my experience.
You sound as if you're clear that you want a separation and I can see that you've come to the end of the stage you were in. Good luck with getting through this next period. I look forward to following your sitch. I'm curious as to whether you'll reclaim the MBR if you're no longer as concerned with how your H responds.
