My son has DEFINITELY prostituted himself for drugs and booze. I was horrified at first and still am, but the humanity in him seems to have disappeared.
He's pretty casual about it-don't think he likes it, but he knows it's easy money and I guess he'd rather do that than flip burgers for a living.
We humans can get used to just about anything, I think...parents included.
But I'm sorry for your pain. It's a devastating blow and NOT what we wanted or imagined for our kids. Hugs...
