While any number of things may be true, there is always the chance the obvious is instead. My mother had to tell me that my best friend had a giant crush on me. Two women were simultaneously trying to gain my attention. The only time in my life that has ever or will ever happen, and I was dense as a brick to it all for nearly a month.

Maybe your son has standards and morals.

Better that than your son knocking girls up and getting std's because he's banging everything that moves. Use it as a teaching point

I lost it at "a piece of my soul died" lmao

Depending on the girl...you might have done well OP...

I know for me, if I had my dad around I'd act the same, maybe come back later? XD also, may be his way of turning her down, maybe he thought she was annoying/ugly or already has interest?

FHL he didn't get any.

Maybe that's more of a success of a father that he did that because he didn't wanna go bang some random chick?

He could be gay or asexual

Maybe your son didn't want to have sex with this girl? I think you may have your priorities backwards OP
