If it's a she then she will try to be mean to you.
If she's not she will ignore you at all costs.
For men it's hard to tell because they will do either depending on their attitude.
just tell your new boyfriend that you still have feelings for your ex and tell your ex that you have a new boyfriend if they really care about you they will understand
He probably still has a thing for his Ex
you just tell him and see if he responds.
she calls you from his phone and tell you
you just tell him and see if he responds.
if you feel like you have done a mistake. And if you have a chance of getting your ex back . Than only..
only if you tell him
tell him that he's not exciting and if he is than o well. tell your ex that u still like him.....
if you are still good friends. Than you can tell your ex.
tell them the worst thing they can say is no
He probably doesn't
you should tell him you still have feelings for him
