If you working on getting your life right with God and your significant other isn’t what should you do? Or what would you do?

you work on being right with god and let god worry about your significant other

my son is an atheist
and my very best friend an agnostic
just do what you need to and let them go their way

Unfortunately for my kids she was Methodist and I am Roman Catholic. We never tried hard enough to compromise. My mother in law strongly disliked Roman Catholic s. My wife had a severely and profoundly handicapped older sister. This was in the fifties thru 1973.RIP. At St Paul's hospital a nun all on her own baptized the child and then came out beaming and bragging I guess about doing that. My in-laws were pissed off. And a lot of people over the years said the could pray her well or asked what did the Mom do to piss off God and she eventually topped all that crap into Roman Catholic (she got me saying Roman) and sat my wife down before we married and said you know he's a Roman Catholic!? Like I was a drug addict or snake handler or Taliban.
Please try to work out something. If she doesn't want to go to church then just go alone. Don't preach but don't hesitate to express the joy it brings if and when asked.

Faith cannot be forced upon another

Grant your love the right to believe what he/she wants to believe. Don't bug them with your new found faith. If you've become a Christian, or revived your earlier Christian faith, be a good example of a follower of Jesus Christ. Show how happy hour faith has made you.

If not married, move on and separately.

My mother believes and I know better. We get along just fine.

Leave. You become like your friends
