Qwerty, sorry you are feeling lonely, that is how I felt in my marriage.
when you talk about having to drag her to couples counselling, you having to take the lead all the time and no sex for 8 months I wonder what the 'working hard' means - what is she doing to merit that assessment?
what shit is she working out - her relationship with her girlfriend?
you could try setting a time frame rather than leaving it open ended. That is what worked for me. I wasn't getting answers, as usual, and so I said you have three months to give me answers. It didn't get me any answers but it put the ground under my feet. No answers was my answer.
