In addition to what useless me said, I am an atheist but I still became involved in our universities chaplaincy... These places are welcoming to all and are usually full of educated people of faith so you will be welcomed for you rather than what you believe in (it's about mutual respect). Met my wife from ours.

I don't necessarily agree with useless me on the bf front though (in this case he might be right but I have a different view) You're both young and understanding come from experience... Only you can be the judge of the following but if he has qualities you love and respect then see how it goes... If he's trying to understand and support you then that is a positive.
