One of our R issues was that I was definitely the only responsible party, to the point I felt like if -I- didn't do things, they wouldn't get done. It was a major part of why I started to pull away from him, because talking about it turned to nagging about it turned to being pretty upset I was living with a purposefully helpless adult when I needed a partner.
Anyway, when we split he told me he felt like I was his mother; I cooked and I cleaned, but we were "never" physically intimate (a gross exaggeration, I note). I asked him if he thought I enjoyed that role, and he had no answer for me.
Maybe some of the same stuff is going on in my sitch.
