If you've been talking for a few days back and forth then they gradually pull back (fair enough, they're not that interested. It's fine) do you just unmatch? Or do you say goodbye or 'nice to chat but don't think we're on the same page' or whatever?
Normally I would just unmatch after a day if it's obvious they're not going to get back to me. Is that rude? Does it matter if it is? I don't know them or owe them anything..
I'd have to wait for them to respond back again because otherwise I'd not know if they'd seen it so it would be pointless. And I'd hate them to think it was attention seeking (a bit like flouncing?!)
What do you do?
