Has anyone been able to have a true lasting relationship with a Christian after admitting they don’t believe in God?
No, it doesn't work. You can have a relationship with a weak believer but, never a christian.
I tell everyone that I am agnostic. I really don't care what anyone thinks. It's my own personal belief, and has nothing to do with anyone other than myself. If I meet someone who I may be interested in I would rather be upfront right at the start. I don't believe in stringing anyone along.
I haven’t talked to many people about my beliefs and I will sometimes mention things to see reactions. I have only dated men that believe in God. Living in the Midwest there isn’t many opportunities to date otherwise. I would like to just have conversations with more like minded people in my area which is hard to find. I just wanted someone else’s opinion. ?
