So I like this guy, and he likes me back, but he has a friend that is a girl that has friendzoned him. He has had a crush on her for like two years, and they spend ALOTof time together. They have never dated, and i don't see that changing any time soon. I don't know if I should start to go out wih him, and hope he stops seeing her so much, or give up and move on. He's really nice and sweet, but I'm afraid that he will end up braking my heart if she ever changed her mind about being with him. What should i do?
