Ignore him/her
Well if you dont like your ex anymore then let them date. If you do still like your ex then tell your sister why you 2 broke up and ask her kindly not to date them.
act cool and calm. if you like him/her, dont show it unless they act like they like you too.
That means he still loves you and wishes you were together and you dont have to still like him because he does just move on and you wont feel guilt its part of life(:
Ignore her and move on. She is an EX for a reason!!
ex means not anymore, so exboyfriend, boyfriend not anymore... exgirlfriend, girlfriend not anymore.
it depends.. if he broke up with her noooo. you must not go down that road unless she says its cool. I think you can if she broke up with him because that must mean she dont like him anymore.
If you feel like you can't trust anyone, you should get counseling or therapy.
ex means "not anymore" ex-wife:used to be your wife but is not anymore ex-husband:used to be your husband but is not anymore lets say I pointed to someone I used to go out with and broke up with them, I would say the person is my ex-boyfriend/ex-girlfriend
1. Act like you don't care you're not with him anymore 2. Flirt/get with his friends 3. Do your best to find someone new, and show him off
well if she likes you back then go get her! you are none of your ex girfrends business anymore
just go out with him. its not her business. if you really want to you should follow your heart. if shes not your best friend anymore then who cares? everyone has a ex.
just move on honey
