what can i do about it?

I'm afraid there's nothing 你 can do about it. Don't try to break them up and destroy their relationship because the guy 你 like will then never like you. 你 just have to except the fact that they're together and get on with your life.

Continue to like this guy. There is nothing wrong with it. If he breaks up 你 can be there to console him. Make sure though that 你 don't hang on desperately for long periods of time. There are other 鱼 in the sea. Make sure that 你 give someone else a chance if necessary.
