ok..but still don't know why this forum is so hostile.. im not obsessing i just asked something.. anyway thanks for your advice
Not everyone here is hostile.
It seems he might be interested in only a casual relationship with you. He is obviously playing the field if he was flirting with other girls in front of you. Be careful how you proceed, he doesn't seem to care about how you might feel. He might be friendly and sexual with you until another girl is around then his attention might turn to her. Just from what you explain this seems to be the case. Just don't let your guard down if you continue being friends with him.
