Teko nailed it on the head. He wanted in your pants, you said no and he's moved on.
I think you had posted this story two times before--------- anyway, I think that you have your answer. He seems to be saying to move on by not texting you. I'm sorry, I"m sure that hurts your feeings. I hope that you meet someone that moves at your pace. good luck
So in the beginning he was obsessed. Texting someone all day and night to the exclusion of anything else in their lives is obsessed. Then you met him, hung out, You said no to sex and since then it all fell apart? Yep, he is not that into you and you need to move on. He wants a boy toy not a relationship. Your best to get on with your own life.
Honestly, meeting guys on the internet is always iffy. Seems like he just wanted sex. but im not completley 100 % sure. but sounds like hes very good at sweet talking. id prolly just stop texting him and let him make the first move, if he doesnt then jsut move on. your gonna get hurt by putting yourself out there like that. Good luck
