Ok, this is part two of my boyfriend question?

What I really wanted to ask was that if I should tell my family I have a boyfriend. My parents are Christian they already know I'm gay and don't care if I bring a guy to the house, but I've been keeping him a secret for the past couple days now and I actually met up with him in secret last night, and it's bugging me that I feel I have to keep him a secret because of them, I think they'd be happy to hear that I'm seeing someone but I'm kind of worried about some other stuff. Help please.
