I need a space to say what I'm really thinking. Really. Thinking.

How do you tell someone, while in a relationship that doesn't make you happy, that you're sorry about her divorce, you know it's going to hurt, more than she realizes, but that I would drop everything to be with her for the rest of my life?

That is literally and figuratively a loaded question.  It burns.  It hurts.  I don't know what to do.
