Well, before you'd even written all that, I'd decided that it *was* time to stir things up myself. So, at the weekend, I wrote her a tough letter, telling her *exactly* what I wanted out of my marriage - which included regular sex amongst other stuff. I told her that I wasn't happy to rattle along in a relationship like this. I made her completely aware about the feelings of rejection she was causing me. And I put it in no uncertain terms that if things carried on like this, then it would all go pear-shaped again.
I also made it clear that I wasn't expecting things to change overnight, either - but that we needed to work on getting ourselves to a point where things could begin to change.
I was expecting it to go one of two ways. 1) it would have caused another same-old argument where I'd have finally thought enough was enough, I'd have packed my stuff, and walked. Or 2) she'd come and give me a big tearful hug, and then slowly begin to ramp up the the physical affection she used to be able to show me, with a view to getting us back on an even keel.
