So lost with my relationship right now. Need some advice😔

So my boyfriend and I have been together for almost three years now (we're 20).

We've definitely been through hell and back, but we've also had very good times together that I wouldn't trade for the world.

But recently it's been getting bad.. and religion has a big part in our bad/hard times .

He is a Christian. A Salvation Army Soldier. His whole life revolves around his religion and the Salvation Army. He is so involved with the SA, always has been, always will be.

And me? I'm not religious by any means. I was not raised in a religious family.

Today we had a fight, and it ended with a talk. I asked him if he thought the religion differences were an issue, and he said yes (he's always told me it didn't matter to him because he loves me, but now he's actually telling the truth about it being an issue).

I told him I really want to try knowing Jesus, but I need his help. I need help finding my way into this whole Christianity thing. He said he'll try to help me, but he's never been good at communication.. another issue in our relationship (with him, not me).

Anyway, what I need advice on is should I try to change who I am spiritually to make this relationship survive? Or should he just be able to accept me for who I am in every way? I love him so much, more than anything, but I just don't know what to do anymore. Our relationship is so complicated in many ways. Any advice would be very appreciated 😞.

Please no hate or judging.
