Stupid is, stupid does

I'm walking out of the gym, I see him talking to one of his many friends. He quickly ends the conversation w/ his friend and comes over to my car , he gives me back my cell phone cover I had lost in his car last year and "my" panties. Funny thing- it wasn't my panties!!!! I quickly gave him back the panties grossed out and told him it wasn't mine. He insisted that it was mine cause it was pink, thong from VS and XS. Well- I wear small, he was always not a detail type of person. Anyway, he was mad that I told him to give it back to one of his many sluts. He said, he has been "true and had never slept with anyone in his bed or anywhere" and it must have been his roommate's friend who brings his gf over and uses his bed. ...maybe? How freaking disgusting even more....ewwwh! He asked me if I trust him with his answer and I said NO! He angrily walked to his car and drove off very fast. I came home, vomitted and took a shower. What a day!
