I have probably asked about this about 3 times already, and I know it might be wiser to drop it and forget about it, but I cant until someone helps me understand this.

I went to visit a friend of my moms. She is married and they have a teenage son together. He looks nothing like them.

She was extremely friendly when I went. Keept feeling my arms and telling me im jacked, calling me handsome, touching me, constantly grabbing onto my arm, etc. I took it for extreme friendliness as she is from Europe and her husband seems pretty alpha so as an older man, and a professional, I didnt think it would ever cross her mind to fuck me since she has him.

Now that I left, and I look more into it, I dont really get them. They sleep in separate bedrooms, when I was there I never even saw them look lips once, hug, not even touch each other. She doesnt have his last name, they dont even have one single picture together out of hundreds on social media. It almost seems like some sort of agreement. Also she has tons of very "tempting" pics on facebook with lots of people(Guys) comenting very bold stuff. Just seems a little strange. Am I so infatuated with this older woman that I am making up all sorts of reasons why I should have fucked her? Im just beating myself up for not having the balls to at least attempt a move on her and I keep beating myself up about it.
