Does this mean we're friends?

Okay, this girl used to make fun of my pics on myspace and the things I said. Awhile ago there was a sleepover and we were both there and I told her about this guy I used to date Joseph Lindon. A long time after that we didn't talk. Then out of no where she asked if we were still going out. I said no. And she asked when we broke up. My friend was there and said "She never was going out with him, and she's a big fat liar" And I said "you're thinking of a diff. Joseph. I did date Joseph Lindon, NOT harvey." And the "popular" girl nodded at me. She also accepted me on facebook. does that mean we're friends?
