What to do now?

I'm in a situationship with the man I'm seeing now.

He constantly acts hot and cold. One day he is extremely affectionate and the other he acts like I don't even exist.

Once I overreacted a bit when he "joked" about texting with others. I told him that they are going to be his toys now.

He now told a friend of mine that I'm crazy, maybe because I went insane because of his attempts to drive me crazy. He always drives me crazy then acts surprised how I acted.

Should I tell him anything about this?
