What Is Strength?

I've always thought of myself as a strong person. I never took shit from anyone, I stood up for myself and my friends, I stood up for what I believed in, I made my voice heard, and I never believed when someone told me I wasn't good enough. What happened?

People still tell me that I'm strong, but if I really was why in the hell am I still here? Why do I allow him to keep me in what I feel is a hellhole? Why do I accept "decent" when I really deserve amazing?

I should really be strong for my son. Growing up with a broken home isn't easy, by any stretch of the imagination. But would growing up with a miserable mom be any better? I tell myself that if we did split, we'd be civil. We'd keep the peace so that he wouldn't have to go through what I did, but I doubt it will end up like that if it happens. It will end up in an all out war. Of course I already have the winning edge since he willingly gave me custody a year ago, but I doubt he'd just sit back and let me keep it.

At what point am I supposed to say I'm done?
