Jealous of my guy-friend

OK...i was the same way with my guy best friend not too long ago. he had a gf. I got extremely jealous. I realized that I wanted to be his girl. I told him. he rejected me because he loves his new girl. but he said he would always have feelings for me. One nite we ended up making out and he hasn't told his girlfriend. He stopped talking to me a few weeks after that after he said he wouldn't. and we haven't spoken. I'm starting to move on now. I met a great guy and everything. Girl tell him how you feel and see what happens. If he wants you, then great! If not you must move on.

Look I have been in the same situation
its you just don't want to share him or his friendship you might secretly like him and just not know it yet.

Do you feel jealous because you want the girls he's seeing to be you or because you miss out on the friendship when he's dating?
