And the feeling you get about him, beyond sexual passion,
and beyond charm,
and beyond intelligence, money making ability,
and all else. And his history of behavior with other women. And what he actually DOES with you, not what he says. Personally, I'd look to the models he got at home, both mother and father. How does the the father treat the mother? What are the family values? Also, does the person you're interested in seem to be psychologically healthy, or troubled?
