Just wanted to clarify my own comments above on the "flirting" thing. I wanted to make it clear that I only said "acting" on it would be wrong. There's nothing wrong with some harmless flirting right now, and it may even help you realize that you're still a sexy, attractive person deserving of some attention. So long as it doesn't ESCALATE, I don't see any harm.
I too am a HD spouse who's LD (hell, NO-desire) spouse is the one who cheated, last summer. I know how it feels to have someone who rejected you for years, finally find the "passion" switch, and they flip it for someone else and not for you, who's been hurting so much. It's not that uncommon, though, from what I've learned.
