Not my first love, but yes, i do think back of significant exes (2 of them) quite regularly. Sometimes wish i could turn back time and change the situation. Sigh!
Somemore i broke up even longer than u did.
I think some ppl just leave a stronger effect on us... 
Actually, can't even get a comparable love story after so many years, and feeling so loved up as i did back then! haizzzz
