Man is Born, Man suffers, Man Dies

It's not that I don't like love, or happiness. It's just that I am having a hard time moving forward. Moving on isn't hard, moving forward is. Moving past my bad experiences, moving past the fears and insecurities they created. It's hard to see someone going through something similar to what I just finished going through that didn't end well. I don't want to poison people against things that could result in amazing life changing circumstances, I just want them to be careful. When I see or hear things that are identical to what he said to me, my instincts start screaming to run away.. This has very little to do with how well I know someone, it's just instincts. So I'm trying my damnest to not run away screaming. I'm trying insanely hard to be supportive, but it's hard. I'm emotionally damaged, and after the fiasco my instincts got me into last time, I'm not exactly trusting them right now.
