i dont think talking about exes is a good thing cozz theyll get angry man... theyll think 'why u alwaus talk ab iout ur ex for? he is the past and im the present ' etc etc its just a sign for arguments so id rather shutup
One of my ex's was a real JERK. I don't talk to him anymore... but when we see each other.. sometimes we say hi.. it's really awkward though.. =/
