I feel the same way, honestly. I don't enjoy the hugs, but I do go through with them and sometimes even offer them myself. The hug isn't really the point; I just like these people and want to let them know that.I'll be honest, for a lot of the time for family hugs, especially now, it definitely ends up feeling more like because of obligation than anything else.
(...which comes down to another problem of mine. I am fairly certain that I've never directly said 'no' to my family, at least in any significant capacity - unless there was another obligation I'd already made that conflicted. Even now, as an adult.)
I don't think I ever really became my own person, even the HalfPerson that I feel like I am now, until the day it really sunk in that being afraid of Dad would accomplish nothing. He'd still be angry at everything I did, and there was no fixing our relationship. Things only really got better for us when I stopped caring what he wanted or what he thought as my father and started thinking of it in terms of a business transaction. He's a self-made man who knows what he's doing, and I can learn a lot from the guy. So long as I'm willing to be the butt monkey for a little while longer. And hey, he's barely home anymore anyway, so that's a plus.
I spent most of my high school years curled into a ball, crying and certain that I was going to die in a ditch somewhere, cold and alone, an abject failure that did nothing but drain and burden others. Still not sure that I won't end up there, honestly. But I'm hopeful that I won't, and I know I help people. That's a start.
