1. Reinitiate physical contact as if we are happy couple. She will either go along with it and I break this two year drought or she will be unwilling to, in which case that will be the straw that breaks the camels back. 2. A more direct version of 1. I tell her that I do not want a sexless/loveless M. It is not an option going forward so either we find a way to reintigrate it if we are to survive. 3. Tell her, that I can see she is unhappy and that although it is not what I want she should leave me if she wants out. 4. Talk to her and ask is there a way to work together on making this better 5. Do nothing......nothing direct. 6. Tell W I am fed up being alone and explain this etc.
I think you need to work through what the consequences of each of these will be, how will you react either way and then what will you do?
