because you'll probaly had a bad break-up
you don't, move on
it depens on what made you 2 separate if it was just to have a break then give him another chance
Y did we ever break up?
The best way to prevent revenge from an ex girlfriend is to have an amicable break up. Do not bad mouth the ex, do not make her look bad in front of her friends.
If there is no chance of the two of you getting back together then you will have to move on.
bad luck
You had your chance with your ex girlfriend and now she is with your friend and until they break up it's 'hands off.'
Chance are he went out with his new gf to make his ex jealous, and then dumped her to show he's available to his ex as he wants to get back with her.
If he can put the past aside there is a chance, but that takes time.
Meet up and discuss things.
he wants a 2nd chance and give it to him depending on why or how bad the break up was but first ask "whats been going on in your life" and that should say if he has a girlfriend or not or he coulld be over the break up
