I would echo all these wise ppl - no to an email. Too easy to forward and misunderstand. Friends usually feel sticky bout this stuff too, but if it's a close one, that was tight with you both, maybe hang out with him/her and not make an ask right away, see if the conversation about you guys is something they are interested in or passive about. I was lucky that my H's friend inserted himself, but most people don't like the middle. Kind of made me wonder what good all that promise of support was at a wedding :-/
G, when was the last time you and your H got together for some eye contact and what not? You mentioned the idea a while back, I think before the concert observance. Right now I'm a hammer and everything looks like a nail to me but if NC isn't doing it, and you feel strong and solid and GAL...just saying.
