No, You live in a very small (area ) city!
It is not fate. Is it fate if someone that your ex never met bumped into him? Should they take that as a sign to get together? Of course not. Fate means that you have no choice in the matter of your destiny, that no matter what you do...your life will pan out a certain way. If fate is part of the equation, then you wouldn't have to bump into him at all, because fate would dictate that things would work out a certain way regardless.
Yep sometimes some of these things are like signs given to us like fate and that we should try and work out what they mean or take the hint.
