Hey Eyes,
I pop in occasionally. I'm afraid it is a way I procrastinate from doing other stuff I should be doing.

My SSM has been a thing of the past for almost two years now. My experience is that sex is about sex. It has all the benefits that it brings with it and it's worth it in and of itself. It doesn't cure other ills and it can't be used to avoid other problems. People behave the way they are going to behave until the specific behavior is dealt with directly. There may be a "honeymoon" as you aptly called it, but ultimately the honeymoon will end...even if the sex continues. So if the passive-aggressive behavior is a familiar behavior pattern for him, I'll predict you'll have to confront it as a separate issue from the sex issue if you want it to change.

Just my experience.

Best wishes, MPT
