You probably need to ask a LBH who has come through to the other side of the pain. By those I've observed in my family members, the DB board, friends and co-workers, it seems every person has their own capacity to withstand pain & rejection. IMHO, a person needs to be their own best friend and work at filling up their time with other things to get through the journey. You may never stop completely loving her, but right now, loving her at a distance might be what you have to do.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
