First of all, you should not be in contact with you ex, if you two have decided to move on, you should be out there seeing other people. However, in your case it looks like he is still interested in you and wants a comeback.Listen to your heart.
FIRST, ITS KINA WIERD THAT HE JUST STARES AT EVERYBODY LIKE THAT. Secondly, if he smiles only at you, it means he probably likes you.
No, he is undressing you with his eyes.
She flirts, stares, smiles...etc
if he stares at you so much and smiles at you
He's interested.
If he talks to you alot Flirts with you smiles at you bugs you stares at you
Usally if a boy smiles and stares at you and likes to hang out with you
If he stares at you a lot. Smiles at you when he knows you are looking at him. And if he looks at you like "WOW"!
It means he has a MASSIVE crush on you.
If your in a crowd and she chose to stare at you There might be a good chance that she likes you. If not then maybe she is really nice and smiles at everyone.
He's lying... he likes you and is afraid... Or he's a stalker lol
no
