Trying to understand..i can't

You know, it’s funny how shit happens. Your in the moment, it’s a situation happening, someone makes you feel needed, you address the issue, have it taken care of and then for what? My mind, while racing and slightly irritated, Im still not moved. See I have heard of situations and domestic violence issues, but me myself through the grace of god has never had to experience this first hand. I feel so stupid in a sense, and also torn between two feelings. I want to close the door on a friend but I can’t. But there is nothing more that I want to do at this point. I wanna say fuck it you dumb bitch, but I can’t. I wanna say your better then this, but I wont. I wanna say there is someone else out there for you, but I refuse to do so. Yet you pride ur self on saying that I am your friend and you put me above others but then u don’t do that. Now im not asking you to do as I say at all times, but I am saying look in the mirror, look at the deep gash in you neck that was infected. Look at your arms, and all the marks that are slowly fading away. Look in you bathroom of your new apartment, the flower pot that was the color scheme for it, broken out of rage. Who are you? You’re not the smart person I cherish as a friend. You’re not tough, you’re little. Your small, your nothing. While to me your everything, but to her, a punching bag. I love you dearly but I just can’t fathom what you could possibly gain from an abusive relationship.
