make them jealous and make them realise they love you and your the one :)
Have sex with them
Only your ex can answer this.
I am a girl and i would NEVER get back with my ex.
Justin Bieber is not back together with his ex. They are close friends, but he is still single.
You don't, move on.

If you don't want to get back together with your ex, then yes. You are over them.
It really depends on you do you want to get back together with him?
Only if your ex is still interested in you, if he/she is, try your best in getting them back.
I know exactly what you mean. Look and see if they look happy together. If they do as much as it hurts back off. If they aren't happy or arent together alot tell her/him. Yolosdra. (you only live once so don't regret anything.) I would tell her/ him though.
You can call her and try to talk to her about getting back together.
You shoot the other ex with a MP5K
Ask them.
