I'm often told that I'll just be (more) hurt, rather than if I were to walk away at the first sign of an end. They're not wrong - I often get hurt.
But hurt isn't the same as regret, and the key is this: I do it for MYSELF, not for the other person, or anyone else.
If I give my all, I have nothing to regret. If I don't... I will always be left wondering, "What if I'd...?"
But that, of course, is just me.

Every choice, "mistake" or otherwise, leads us to here. To who we are. Personally, I have some stuff I regret in my past, but if I were given the chance to change them I wouldn't. I wouldn't risk changing where I am or who I ended up as.
