As long as you make sex with W about OM, I think your sex life is pretty doomed.
And, as long as you continue to accept a sexless M, I think your M is pretty doomed, especially now that you are back in school, which is extremely hard on any M.
So, unless you are able to both move forward by making a sexual, loving R about you and W and the future, rather than about OM and the past, and to stop choosing to live in a sexless M, then, I really don't see much happening for you.
Of course, I don't really see a successful sexual R between you and anyone unless you change your views about the role of sex in a relationship. So, maybe you really are better off working out your problems with sex with your W.
