Boy problems

So I had this guy friend and it was a group of 4 of us that used to hang out(2girls and 2boys) until my best friend got a crush on him. The whole school found out and they told him and some of his friends were trying to push them together but he kept pushing it off. Soon I realized that I had a crush on the same guy but didn’t tell anyone because I would seem like a bad bestie. After everyone found out about my best friend’s crush the group started to spilt but the boys got closer to me and further from her. One thing lead to another and the guy told my friend that he doesn’t like her and she has no chance. So now he broke her heart and he no longer hangs with of now it’s just 3 of us hanging. He doesn’t even speak to us but he stares at us all the time and im always making long eye contact with him. It really sucks because I still like him and my best friend wants me to talk to him so the group can get back together but I don’t know what to do or say, HELP
