Wow I'm very impressed by all the responses so far. Thank you ((Belle, wontgiveup, Byz, notablackbarbie, Madisgram, JD, notz and bloom3)).

I don't think I've had the pleasure of reading such wise advice all in one thread before - all the wise quotes, personal stories and analogies.
Usually when I start a thread, I'm anxious to read the replies. I think I delayed myself, because I'm afraid of confronting this problem. I think I basically gave up, on ever trusting anyone and became an island - depending on my own strength. I sometimes feel like an abused dog cowering in the corner. I agree it's not fair to assume I can't trust some people.
I figure if someone from my own family can betray and hurt me, then how can I expect any better from someone not related to me. I will reread all of your responses and hope that slowly this might loosen the chains around my heart. Thank you everyone.
