Chris: It's been 14 years since my lounge lizard, er, ahh, I mean dating days, but I'd think that "he" would not have "friend requested" you (Boy, is all that crap fupped or what?) if he saw you as a potential interloper.
Beat him to he punch if he is her guy. Make him think you're awesome (and even aloof as far as she's concerned). He'll re-confirm it all to her and torpedo his own ship, if he is, in fact, even sailing one.
OK, OK. So I did a lot of this.
Oh. We might think of starting a "Rumination" thread so this insteresting, but off topic stuff can keep clear of everyone's alpha-numeric recapitulation manias (M-that VP-this...).
