if he looks at you alot. stares at u and wen u look at him he quickly looks away or looks down. if he trys to make contact with u. maybe a touch on the arm or shoulder. if he always ends up where ur at or in the same room. or if his friends always looks at u or trys to find out information from u. Depends. You want the fast way or the slow way? Fast: Walk up to him and ask him. Hey I never said it was easy. Slow: Watch his body language and what the person above said.
Ask him
It depends on why you or why she broke up with you. If you cheated - no If she cheated - maybe If you broke up with her for no apparent reason - yes If she broke with you - no
Tell him of your feelings or get out with some friends and forget about it.
make sure that you know he still likes you, and then just tell him how you feel or send him a text or note or email or SOMETHING IF YOU REALY WANT HIM BACK!!!!!!!!!!!!!!!
Well if he broke up with her, she might still have feeling for him so just ask her that your feeling like she might be showing emotions for him and ask if it's true or not. And if you two are in a committed relationship, she should tell you the truth.
She doesn't like you and if she does she's an idiot
Body language is the main things which tell most of the things. If she shows signs of submissiveness and closeness she might still be into you. If she contacts you more often she might still be into you.
just tell him that it dont have to be serious rite away to just date and see were it goes.
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.
bum her and if she likes it u know
don't
well if u broke up with him because of the way that he is acting then tell him that u will take him back when he changes but that is also if u still like him too....if u dont then tell him to leave u alone
Be upfront and tell her how you feel about her and how you really don't want her following you around DOnt worry, if she goes completely insane and stuff just run away people shouldn't do that
