Do I deserve being hated for trying to be intimate with my friend's bf?

My friend's bf is 35 y.o, I have been in love with him for 1.5 years. I've witnessed the end of his 2 serious relationships so far. I've always been intimate to him. I don't know if he noticed or not. His ex-gf was trying to belittle me because she suspected me. Just because of this, our mutual friends said they hate me and we went our separate ways
