"To be vulnerable to someone you pretty much have to trust them
completely"
Devils' Advocate here...I have lain myself open time and time again to others; and I have always known that I would be hurt in the end...I do/did not trust when I am/was open and vulnerable.
I expect to be hurt. I do it anyway. It's okay though. I am secure in myself; I love myself enough...if I didn't risk getting hurt; I wouldn't be living. I'd be what I used to be: an empty entity who does not participate in life at all.
I figure it this way; if I have no expectations, and then something good does happen (Heaven Forbid

), I'm there to reap the happiness of it all.......Pax---theo
