Hmmm...Maybe I do understand it. I was going to say that I've never felt unloved because H wouldn't have sex with me. But I don't know if that's true. There have been occasions when I was interested, didn't state my need, and H didn't pick up on my interest. I felt hurt and rejected then and... unloved. (I do take full responsibility for not having my needs met because I didn't state my need clearly. And ML was my need. ) Anyway, it sure didn't feel good. Had this happened on a regular basis, I'm sure I would have started feeling unloved much like a person with the PT LL.
But back to your point, yes, I can definitely see how he felt.
I think the more our needs are NOT met, the more focused we become in having them met, to the point that others may perceive us as "needy." I think that goes for men and women.
