I called her a meth-head bi**H. I slandered her on myspace. Why is she being nice to me?

A year ago, Lysa was dating my friend whom I was in love with. He dumped her coldly (nothing to do with me) After that, he and I were lovers. I degraded her on the internet. To this day, why is she so intent on being my friend? Do you think she is trying to play a trick? ( he does not talk to either of us anymore to let you know)
