If you and your ex broke up and he looks rough maybe he is having a hard time with the break up.
you can tell if he looks at you in crowds or he says "he knows who likes you" something like that then yes. It also may depend on who broke up with who.
coming from an ex friend, when you see you ex (especially if she broke up with you) its really hard to be in their presence. it makes them think about all the times you had, also he's probs uber pissed at you
It is not clear if you broke up with your ex or if your ex broke up with you. Either way if you are now both broken up you need to accept this and stop texting. What you are doing is harassment.
if they broke up with you, move on. If you broke up with them and they flirt with you, flirt with them back
Brother.
normally spelled ex-boyfriend and its when you dated someone then broke up he is your ex
If you mean by you dated someone, then broke up it's ex-girlfriend or ex-boyfriend or just ex. If you mean you dated someone, broke up, and then started dating again its girlfriend or boyfriend.
If you broke up with he/her before you do yell them off get backup from friends. If he/she broke up with you make them regret it by rejection.
Out, not, or former
it all depends on who did the breaking up, who broke up with who, if you broke up with your ex it would be easier to become from, but you may need to be careful and keep things clear with your ex, such nothng more than friends, if they broke up with you, make sure your over them completely before trying to be friends. It may just hurt you if your not truly over them.
Yes. She broke up with him for no reason
depends on why you guys broke up
