Guy I like slept with my friend to spite me?

We were “talking” for months. And then one day we had a misunderstanding and stopped talking. In those months him and my hating friend slept together. I confronted him about it and he said he only did it to make me jealous and get my attention because he wanted me back. Should I be rid of him for good? I did like him but now I’m put off completely.

He knew she was my “best friend” and did it on purpose. She did it on purpose as well.
