I started feeling the same way, I hope we are not just "feeding" this emotion to each other. After reading many many posts in the forum I changed the way I think about what is happening with W.
Before I was thinking that M had some problems and OM was a consequence of it, so if I could "fix" R, OM would go away. Now I think that as long as OM in the picture I cannot fix M... yes, I can do something about me, and maybe this is going to make W think.... think about me, how I am changing, how "strange" I am becoming, so..... more reasons she has to think about me, more she may think she is missing me. I have to find a sort of a logic in all this, it is my nature.
