There's this couple I know who are into a niche hobby that very few people are committed to in my region. It's a set of activities that are often centred around group activity, and in general, we're part of a good friend group now and have been for a couple of years now. I'm the young guy in the group, everyone else is older than me and come from a different place in life and social life. They are really cool and smart people, and they've been very generous and kind with their time, resources, advice, and support towards me. They genuinely seem to have my best interests at heart, which even among my closest friends and family, I can count on one hand for whom that's true for. Standard beta couple, older millennials, successful senior professionals.

Now, the problem is the wife. Ever since I was introduced to them, she's been showing interest in me, I can feel her looking at me, always talking about me in praise, laughing at all my jokes, touching me, trying to find alone time for us, giving me googly eyes, trying to get me talk about my dating life and interests.

This hasn't been a problem so far, because we only see each other every few weeks at best, and I was maintaining a friendly distance. They're classy people, so she's managed to keep herself in check so far on this. But recently, we've started seeing more of each other, and last night was a milestone and everyone got drunk. Walking around, she started pointedly asking me questions, trying to get us alone, started touching me aggressively, at one point she was practically sitting on my lap and staring at my lips, with everyone around. It was a big embarrassing, and I did not move. When I kept denying her by implication, she withdrew, and barely looked at me the rest of the night.

She's texted me a couple of time to hangout when her Husband's been traveling the last few weeks, and she's been texting me today about meeting up.

I value my friendship with the husband because it's valuable more than her pussy.

She's an aggressive 5. To her credit, she hasn't blown up after marriage. She's a petite little thing who's my kind of cook, and smart, and driven and successful.

What do I do?
