He is almost twenty. Goes to college in CAnada. Says that she was the only woman he has ever loved.

I reacted with internal relief that he is straight. Not because I have anything against gay men. Nope, homosexuality is wonderful and I sign all sorts of online petitions for gay rights, but I know that it is easier in this world if you are straight so I was relieved.

I thanked him for trusting me with something so deeply personal.

Is there anything else that would be helpful to say without being corny and condescending?
