guilty or not, it's nice that your H is considering a V-day gift for you! I hope he picked out nice shoes!
As for the OW, shame on her and all the other OW/OM out there. How can someone live with themselves knowing they are a home wrecker? That they are intentionally hurting people, breaking up love, taking a parent away from a child FOREVER?!
In my blowup the other day I actually said that to H (I was on a roll), I said what kind of a person is she, knowing that he's married and has a child, and still wanting to destroy everything. And that he is attracted to THAT? He thinks he'll find his happiness in THAT? He didn't answer.
Anyway, OW is obviously feeling major jealousy...maybe because of V-day? You are still #1 and hates that.
