So I use to like this guy named nick but we are juss good friends that's it.
I'm going to be his friends (jordan) girlfriend in a few days.
And nick juss told me last night that he has a girlfriend now
I hate that he has a girlfriend it bothers me
I don't like him but I hate that fact that he's not single anymore
Am I jealous?

It sounds like there is jealousy here. When you knew him just as a friend and he is now seeing somebody in the back of your mind you are hoping that he would just stay with you. It is actually normal to have that reaction, many people want somebody that they can not have. This might sound weird but is very true. I would suggest you keep it light. Remain friends with this person but the jealously thing has to go out the window. It is not in your power who somebody sees or does not see. You need to let this go.

It most likely is jealousy. Even though you say you don't like him anymore, its possible you still do and that would be one reason you could be jealous or you could just be scared it might change your relationship with him, but trut me if he is truly your friend he won't change the relationship he just won't spend as much time with his friends or she will just hang out with you, him and his friends.

That's funny, I am really good friends with a guy named nick and I really like him. If your nick is anythinkg like mine, tell hiim how you feel.

You are jealous bigtime and you have a boyfriend? Get over it.
