No, I think she is just trying to avoid intimacy, for whatever reason. When she wants to punish me, she's much more obvious. She usually does this by trying to humiliate me, for example, by continuing to verbally berate me until I do something like agree that I'm worthless. I don't buy into this anymore, although she still tries. Sometimes, she just looks at me with them 'angry eyes.'
I used to think she punished me by not having sex with me, but that's been going on so long that my mantra has become, "what's she going to do, cut me off?"
I think she has somehow convinced herself that there is no way she agreed to one night a week of physicality with me. Just didn't happen.
