what does this mean?

Maybe because he doesn't want you to look attractive to other guys 'cause he still likes you....

Maybe he still likes you or have some feelings for you. Or if not, he see's that your happy and he's not and he's trying to make you feel the way he does. You shouldn't feel bad and you should be allowed to wear what you want to wear. Don't go back to him because he might be controling.

Maybe he was trying to find out who was you wearing for

Hes just trying to be an A hole and make you feel bad because hes probably having a bad time in his life.

he's obsessed and don't you u to look like your putting yourself out on the market like trying to catch some other man's attention

You don't know what you've missed out, until it's gone...There it is...Just smile...Looks like your doing pretty good for him to notice...Keep It Up...

because as the saying goes "you don't know what you got till it's gone" He still has feelings for you he's just not saying it.

jeje maybe because he still feels like he should protect you and he doesn't want anyone else to be checking you out!jeje maybe he still likes you;) or:S lol:)

you answered your own question in a way, he's your EX, he's feeling bad cause he doesn't have you anymore

Its because now you are his ex and he is jealous cuz you probly looked hot and he didnt want other guys to notice you...but guys are confusing...

IT COULD JUST BE HIS WAY OF TRYING TO STRIKE UP A CONVERSATION THAT COULD GO EITHER WAY GOOD OR BAD DEPENDING ON YOUR RESPONSE.
