Dating as an atheist


Hey guys, so when dating do you feel as though it’s important for the other person to know you’re an atheist/agonistic? I been seeing this guy, the topic hasn’t came up yet. Noticed he wears a cross but never outright said he was religious. He had mentioned he’d like to be my boyfriend but I don’t know if that’s something that will bother him. Should I tell him or see if it comes up?
