This is the analogy: If he kindly ask you to offer up yourself
to be prositute, will you do it? If you are looking at him as sex
partner, then just go on. No need for advise from here. But if you
are seeing him as soul mate or someone that u love with your soul
and heart, sorry, both of u are not at the same page. He's looking
at you as someone who can satisfy his sex need only.
