K I'm just gonna go for the elephant in the room...I agree with everything said above but just want to add, maybe he's married? or has a gf? Already? And he got caught? I mean it could be he's just not that into you, but usually men (even the ones being chased) if they're sexually interested the first time, they don't let that dry up and rarely if they are being offered 'no strings attached' sex.

He could be different of course.

Or he could have an SO and he's not willing to mess that up for you...sorry to say that so harshly...even if it came with no responsibility. In any case, it will be difficult...I'm going thru the 'no contact' thing myself right now..and I'm crying one minute, furious the next, numb and mumbling next....but stick to it. You'll feel better about yourself and if he does contact you, for whatever reason, you'll receive the respect you deserve.

Rikki Lee Jones has a good quote: '...if he offers it take it, but honey don't give it away if he don't appreciate it...'
