Why do I love her so much?

Okay, so this girl who i loved for 2 years is not the best person. Shes, lazy, shes inconsiderate, she can be a very big *****, and childish. Yesterday me and my friend talked for about 2 hours all the things she pisses us off with. It was great to talk about, my friend doesnt think shes the best looker but I think shes BEAUTIFUL. Like, im trying to basically trying to get with someone else but, no matter who else i look at or how much a ***** i think she can be, I still love her.
