Love triangle problems

I have problems.

First of all I have my girlfriends, who is very nice, caring, funny and loving towards me.

I have another friend who is a girl, which I love so much- Im always happy to see them, Im happy to be around them. If they sad, it makes me really sad. If they are happy, im happy. I dont think they share the same feelings towards me!

What would u do, stick with the loving and caring girlfriend or try my chances with my other friend who doesnt seem to have the same feeling?
