That's what I think! She's just overwhelmed, that's where all the feelings of unfullfilment come from. Nothing in her life can come to "completion". As she finishes something at work, two more things get dumped on her. And with kids and the house, well - that work is never done. I want to tell her this, but I don't think it can come from me.
GG,
She does get a backrub/footrub/neckrub almost daily. I can just see it in her face that she needs it. And granted, on occasion it does lead to more, but for the most part it's innocent.
We are still intimate, so those on those times I get the feeling she is asking for more, (ie - closing the door behind us and stripping down before getting into bed when I offer the backrub) I'll "up the ante" - but otherwise pushing the issue would only make the backrub itself a tense issue.)
