I need Help😔😭

Madison • Everything will be okay.
So recently I came out to everyone to tell them I was Bisexual.
Me and one of my friends liked each. We started dating and all of my friends don't like her and everyone is telling me to break up with her. But the thing is, I really like her and it had been so long since I have been happy. But I want my friends to be happy cause I know how it feels. I really love this girl and I don't want to give her up. What should I do?
