Is this betrayal?

So I have a crush on this guy whom we live in the same apartment unit and we have been seemingly getting close. So the problem comes is that my friend knows that I have a crush on this guy actually scratch that I am in love with him but they hook up now I know we are not dating but couldn’t she at least respect the fact that I like him and the worst part is that she has a boyfriend and her boyfriend told me this and before you judge the guy that I have a crush on he doesn’t know that I like him nor does he know that my friend has a boyfriend. Honestly I feel betrayed even though I am not dating the guy. Is it right for me to feel this way?
