Went back through your posts to try to see when this downhill slide started. You had a lot of very positive posts in late June. Early July seemed to get more negative, but some positive ones as late as mid-July. Since then worse and worse. I didn't notice any particular triggers, just general crappiness from your H, but was there anything in particular that has spurred this?
Here's a question. How much of all of the problems would seem so much less consequential if your sex life were good? You rant about many things, but how much would be solved if that single area was improved? Please understand, I am in no way minimizing your complaints. But I think your perspective might be much different if you had the satisfaction, intimacy, and love that a good sex life might provide. Other problems would seem so much smaller, and your life would feel so much richer. What do you think? Am I oversimplifying too much here?
My perspective is radically different when that part of my M is going well, as compared to when it's not. I wish it weren't so, that I could keep a more even keel regardless. But it is, and I wonder if it's that way for you too.
I don't recall all of what I'm sure is a long list of things you've done to try to improve this area of your M. I'm sure you've tried to get him to read Michele's book. Has he reacted positively to anything? Is he willing to work on the problem?
