Maybe I think I've got feelings for her. But im trying to deny
it myself as I dont want more than that plus I dotn want to rui
nthe friendship. But this guy seems to be like making our frendship
drift apart.
If u want her to prioritise u over him. Make her yr
gf. 
Do not expect too much from a friend, even a special friend.
Only when she becomes yr ger, u can dream more of what u want and
expectation!
But as what u say, u do not want to jeopardise yr friendship.
Weight it properly, find out more info of the guy and what
makes him so attractive to yr friend?
