Ya know, I don't think there is any way right now for you TO KNOW, ya know? It doesn't sound like you are at a point with him yet to even talk about R, let alone sex.

From what you just said, it sounds a bit like depression, since he has distanced from friends too, but from our virtual vantage point, it sounds like the fog is lifting a bit, NO? Depression often does cause ED, as do many other physical, emotional and (for some men) relational factors. I just tossed that out to see what you thought...not to stir up your sadness. (I've been there and know how you feel, BTW)

I say, regardless, just file the thought away in the back of your brain and don't dwell on it. Carry on with the detachment/dim thing since it seems to be working. Leave out your receipt and, while he's home, disappear for a "date" with Keith Urban. Keep him curious about you.....here kitty, kitty... (to quote others on this board, tee-hee)
