Okay. So, he is good looking and SEEM wealthy. Not a BIG deal if there is no connection. You are desperate for him for all the wrong reasons. You know nothing about him and you are too willing to sleep with him. He is probably losing interest because you are giving sex to him too easily. Not making solid plans is a huge sign of low interest. I don't think anything good will come out of this.
I haven't given sex to him yet. And I made it clear to him that I am not gonna sleep with him on the second date either.
