Girls i need help with boys now!?

It sounds like hes being fickle ... something better has come along so he has 'sacked off' your friend. If this other girl knows your friend likes him maybe she is just trying to cause trouble and wind her up. Tell her hes not worth it. if he really does like her he wouldnt be prefering this other girl. Give it a while and see how he acts see if he comes back to your friend if he doesnt then he isnt worth it. Good luck xx
