I'll just throw it out there... some people don't trust anyone, and if that's really how you work, ALL your relationships will fail. Not just romantic, either... work, school, everything. The first person you have to trust is yourself, and that's not something done easily. We have a harder time with that than with any other facet of trust. Sometimes you have just let go, trust, and leap... I know, it is very Jedi of me to promote this, but honestly, what's the worst thing that can happen out there? I'd rather fuck up a few times than not take the shots, I suppose.
