A while back there was this cougar the gym saw her often during my workouts. Tried to shoot my shot, and my approach was pretty terrible ngl, and gave me the "I appreciate the compliment, but I'm married" spiel when I asked her out.

Whenever she would see me in the gym however she would always flash me smiles etc. Hadn't seen her in a long time until yesterday.

As I was finishing up my session and on the way out, she lingered around the front desk until I left. Then she approached me in the parking lot, saying she hadn't seen me in a while etc, and talking about how much bigger I got. I didn't really push for anything, since I was in a rush.

Gut instinct says it's just validation seeking, but I'm pretty clueless on this shit. Thoughts? Advice for future interactions in general?
