Honestly, I can't say i've ever been seriously hurt in any relationship. Sure my childhood wasn't all peaches and cream, but I keep that out of my relationships. I've been the same way all of my life. Very few get past my core, and those that do have never really done me wrong. And the one that slightly did, i am just as much at fault as he is. So I don't blame him.
Maybe im just programmed to be this way? I dunno, I've been digging into my issues with commitment for years. I've been able to commit for 11 years and never looked back. Relationship to relationship is different though. It takes a special man to get to me, and I can honestly say those are few and far inbetween. Not saying there aren't plenty of great men, just not what im looking for.
