A friend of mine informed me that one of my ex plates ( from 4 months ago ) joined my gym. So I guess it will be inevitable to meet her randomly soon.

She lost interest back then, I do not know why. It just went no contact, mostly because of her.

How should I react when I meet her? Just briefly greet her and then continue with doing whatever I was planning to do? Should I try to replate her? Should I try to figure out why she went cold? Should I ignore her completly?

I guess the best decision would be to just say hello, act unbothered and just continue to do my thing. Right? Or should I ask her if she wants to hangout again?
