No doubt about that. Even though my W has not been acting very attractively lately, she knows it wouldn't take a heck of a lot of effort to get my attention, though don't tell her that. Me making that emotional connection with her, that's a little tougher.
I doubt she is concerned about attracting you back to her. She knows she's got that.
In fact, I have not heard of a case where the WAS was trying to attract their LBS. It has always been left to the LBS to take care of that dept. The WAS lost attraction for the LBS before their heart left the M. And how many newcomers (mostly men) talk about how they are drawn to their beautiful S?
Her feelings of lost and disconnected has a lot to do with the withdrawal depression she's experiencing. I think she wanted you to fix it, and when you couldn't you became a target for her frustration. It's hard to be a willing candidate to work on a MR when you have zero motivation and feel terrible. This is something she will have to work through herself. Is she on any anti-depressants?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
