You go up to him/her and say:
"Come here Sweetie!!!" (or something like that) You can tell by their reaction.
But seriously, just ask him/her how they feel about you.
you say its my life not yours, if i want to get back with my ex, i will get back with my ex so if you are going to hold a grudge about it lump it
Talk with her , the best way to get her back is to be honest & upfront with her .
You just tell them that you don't want to be with them.
be honest with your ex tell him you want him back. even if he doesn't say ok fine he will appreciate the honesty
go tell her you were stupid and want to go out with her again.
tell her that you are sorry then say you forgive her
Tell her that you love her and that your sorry and that you really want her back
They probably won't take you back, so it's best to just move on.
Tell him you miss him and tell the truth
If your ex wants you back . It is on you whether you want her back or not. If you don't want her simply tell her that.
There is a good possibly your ex may want to get back into a relationship with you again. Be wise and think about it before leaping into another relationship with your ex. Tell your ex you will think about it; do so and then let them know your answer.
If she broke up with u, tell her that u want another chance. If u broke up with her then tell her that it was a mistake and u want to get back together with her.
