As the father of a strong spirited, fiercely independent and incredibly drop-dead gorgeous daughter all I can say is...Some people are only alive because it's illegal to kill them. Don't sweat it for now, not a thing you can do right now anyways. Worry? Damn straight....that's okay, that's what Dads do.....just not too much or it can kill you. Just keep your eyes wide open all the time and be there for her. Do not voice to her your opinion of him unless she asks, and even then, only very carefully. Doing so only makes things worse, besides, she already knows without you saying it. All of the Grey hair I have (99% of what I have left) I'm sure is from her. I wanted to take all of her previous shit-for-brains, douchbag, knuckle-headed, arrogant-bastard, goth worshipping boyfriends on hunting trips. Her current boyfriend is also now her fiance and I have to say that I absolutely think the world of him. I'd take him hunting too......just for different reasons. Your daughter....her choices for boy friends right now may not be as you wish but they may very well change if you are there for her now and keep her close (Not saying that you haven't or aren't now). Daughters always want the approval of their fathers in the end, but, they will test the living shit out of his patience first.
