What should I do?

So I’ve know this guy for a while now and we’ve been on a few dates but it seems to not be working out for us life wise and schedule wise I like him and he likes me but we have a lot of differences like politics and religion I don’t care about the politics but the religion does bother me I’m catholic and he doesn’t believe in God at all I know that, that could cause problems in the future if we were to date but what do I do about my feelings? Also I feel like a hypocrite my family thinks I’m an angel but I’ve had premarital sex and I’ve probably sinned a lot more then what they think. Please don’t judge me to badly I just need to get this off my chest
