"what will you do if you saw your EX inside the mall together with his new gf/bf

If we had just broke up and he broke up with me I would be hurt and probably not speak to him. If the break up had been a while back and I was over him then I would be cordial.

i suppose it would depend on the ex and how long ago. i got married at a early age so most of my exes are 7 years go (when hubby and i started to date). This senario actualy happened but at a hocky game. We ended up becoming good friends now that we were more mature and past the age of teenage vengence.

I would ignore then...and act like I was having the best time doing whatever it is that I was doing when I saw them,.. I would be smilling and laughing...so he would know that I don't miss him =)
