If a guy wants to take an ecstasy with me in the woods, is he planning on raping me?

The thing is, he only wanted to do it if the other friend was there. He's my ex, but he's recently only a slight bit straight, so were friends. He knows I still like him. I invited him to do this with me during school. He joked, "aww no buttfuck?!" when I said I couldn't do it. I need some non-hater advice please.
