Until I learned about the 5 Love Languages it didn't dawn on me that my H was doing his damnedest to make me happy by working overtime/making lots of money (acts of service) and buying me things (gifts) when what I wanted was physical touch and quality time. That's why we were both so upset, because we were both trying so hard to show our love for one another in ways WE understood, not the ways that the other one wanted.
Maybe Mrs Geek is doing things that she misguidedly thinks are loving. Also, when things are such a sore spot any jesting about sex at all can go awry pretty easily. Let's hope she's trying to keep a light mood instead of trying to say hurtful things.
