Jen, I know exactly what you are talking about with the cycle. When I'm sex starved I'm a jerk which makes my W less likely to want sex, making me sex starved and a jerk, and so on in a big circle. I became conscious of the circle in MC at the end of my first M but couldn't stop it in my current M. Its really upsetting to know better but be stuck in the circle just the same. I tried many many times to break the cycle by giving all the things I think she wanted. It made her happy but she would never recipricate by increasing frequency. We maybe had sex 2 or 3 times in that month instead of zero or 1. Despite knowing better I'd eventually become a jerk again.
Things were much better this weekend. At MC Friday she agreed to write an appology letter for the EA. I'm more hopeful now that we can not only get beyond the EA but be happier than ever before. Lots a hard work to go though.
