You do nothing and go on with life.
please be my girlfriend again
Stare at her. Tell her. Be smart
she calls, mails you and ask you out again.
1. Does your ex have a new girlfriend If yes - obviouly not interested in anything with you as is seeing someone else if no - find another quiz
He means he has not got a girlfriend and you split up with him for nothing. No he is not interested, he was being polite by replying to you.
It sounds like there are no signs.
she flitrts with you while they go out
cutting up your best t-shirts, slapping your face, kissing somebody else and shouting abuse messages at you are all signs of your ex still loving you.
While it's not easy to say, he might want his ex-girlfriend back or he may just not like you. Additionally, he may also still be interested in her, so proceed with caution.
You can't "know" for sure without mind reading. You can watch for signs or ask her though.
The ex-girlfriend is the girl he no longer is dating.
