I tend to be very cautious as well, having a history of abusiveness. I try not to be too hard on myself. I'm that way for a reason, and am hoping that I will one day learn to trust appropriately. I say "appropriately" because trusting too easily is not ideal either. And most of all, I hope that for those that I do trust - that I can handle the hurts and ruptures that occur along the way in a healthy manner - and to not fall to pieces so easily.
