I don't love my bf

I love another guy and nothing can happen between us because we live in different countries...also I'm pretty sure he doesn't like me back.

Anyway, I do love my boyfriend but not in that way...he's like my best friend, I never want to lose him but keep him as a friend all my life.

But I realise my feelings go for another man and I feel so bad.

First because it would hurt my bf and also because I can't be loved back with that other guy....and we can never be together...

What can I do?

Any similar situations??
