For context I just found out all 3 of these guys like this week. We have two weeks left in school so I think they feel as if they need to give hints or confess. Guy 1 is someone l like but turned out to be an atheist. I am a Christian so unfortunately it wouldn't work out. But I want to remain friends. I have talked to guy 2 throughout the year yet I don't like him back. Guy 3 I barely even know and don't like him either. I have classes with the first and second guy and don't want to make things awkward. I want to be kind and honest with these guys. How do I tell the first guy that I won't work due to religious differences and 2/3 im not interested.
