I thought I'd post an update on here. The guy in question was clearly not my soul mate, twin flame or whatever. A few weeks ago I saw him by coincidence and he didn't even recognize me, he certainly wasn't interested in me - in fact he didn't even find it necessary to say "Hi". I have also realized that he was clearly a jerk. I have forgotten all about him now. And I think that's for the best. Sometimes we meet a person and for some reason we think about them, but once we know the feeling is not mutual it's pointless persisting. And in this case it's for the best - he was enough of a jerk as that he could never have been right for me.
