Strongly suspect wife of having an affair (for reasons I won't go into here) but can't prove it. My natural reaction should be "I'm gutted", but my actual feeling is "I'm not too bothered".

The reason for this?

An HB9 coworker. She's in a LTR herself (10 yrs, and the guy she's with is her one and only). There has been incredible sexual chemistry since day one for nearly a year now, we've had hot/cold times (I firmly believe due to her ASD) but all in all the signs are absolutely clear that she is seriously attracted. I won't go into full details here but please assume for sake of argument that this girl is strongly attracted and can not stop putting down her bf at every opportunity - she's unhappy and wants another man, at the moment I'm in prime position.

I'm leaving work in a month, after which point it's unlikely I'll see her again. She doesn't know this.

Next week will be the last time we'll see each other out of work. It's a coworker's birthday, partners invited but the fact neither of us are bringing partners speaks volumes.

The problem has always been her ASD and guilt. Despite the fact she clearly wants it, the closer it gets the more she recoils. For instance she told me over coffee once that they don't have sex anymore, but that she's so flexible she can get her legs over her head. Then I get the distant treatment at work for a few days.

This party presents a dilemma. Do I do what I'm told is Blue Pill and ask her what she truly feels, in the knowledge that this is the last chance, or do I just have a normal night acting as alpha as possible but potentially let the chance slip away?

To complicate things, there will be an utter cockblock at this party - a guy who is into her who will take every opportunity to butt into conversations with her and try his luck.

Revealing feelings to a girl is clearly anti-RP but this party feels like a last chance saloon and that if I don't make something happen i will regret it for the rest of my life. So what do I do?
