Is he obsessed?

Ok. I'm seeing this guy who is my cousins best friend.. He asked me out the other jour and I told him I didn't know because of what my cousin would say.
He told me he would ask my cousin.. And I told him not to but he did it anyway.

My cousin was fine with it. But I still don't know.. Lately he has always been wanting to see me kinda thing.. Like non stop..
His a very jealous type.. I talk to one of his Friends and he got so jealous the other night.
But then his friend told him that I'm not his type and he wouldn't go there.. And it hurt me.. And I'm not sure why..

But yes.. My dad kinda a dit his possessive and they turn into abusive boyfriends.. I guess I'm scared?
