Is anyone good at reading 'boy language' ?? i dunno what to think of this :/ help!?

Guys can be very jealous creatures, he's probably just feeling bitter because he knows you'd be able to get with other people if you wanted. Just make it clear to him that he's the one you want and he'll probably be glad to hear the words. But don't go clingy texting him after he's been bitter, wait until tomorrow and start with some general talk to test the waters. Hope that helped :)
