Is it normal to be possessive over a FWB?

I don't love him but the thought of him even looking at other girls makes me sick. I want to be the only girl he wants. I want to feel like I'm so beautiful/good in bed/fun to be around that even though he's not with me, he can't seem to find anyone that compares. I don't want to be with him, I have a boyfriend already, but I spent 2 hours crying because he called my friend cute.

Is this normal? Or do I love him and don't realize it?
