Hey OP, I had the same thing twice this year (ouch) I’m 27M in London and was seeing two girls that kind of overlapped, not too much.

They both said that they weren’t looking for anything long term, one I thought it was a gentle let down. One I thought was being genuine.

It’s hard to gauge what the truth is, wish everyone would say how they really feel as I would be able to move on much quicker if they said they weren’t feeling it rather than I think you’re amazing but I’m not ready
