My (38M) girlfriend (31F) wants to return to abstinence after 1 year as a sexually active couple and we just bought our first home together

My GF and I recently bought a new apartment together. We wanted to move in together and the rental market is unstable right now so it seemed like a good investment in our shared future. We have been together for around a year and have been discussing marriage for a while.

We've had some relationship issues recently, largely caused by my negative attitude. Not least, I found the whole home buying process stressful and didn't handle it too well.

She told me she was religious when we first met and had abstained from sex prior to her first marriage. She was coming to the end of the divorce process when we got together and had stopped going to church at that point. Our sex life and intimacy was always great and while I knew she still held her religious beliefs, they never got in the way of our relationship.

We met over the weekend and I helped her move her things in and then on Sunday night she told me she wants to reconnect with her faith and that would mean abstaining from sex with me until we're married. For various reasons she also told me she doesn't feel ready to marry me right now and wouldn't be able to marry me until next year at the earliest. She has told me I'm welcome to pursue FWB arrangements or seek "professional help" elsewhere during this period while we still retain the relationship and live and share a bed together but that's not what I want. She is also offering to buy my share of the home if I prefer to just leave and we can go out separate ways?

Any advice? This has totally come out of left field and I have no idea what to do. I love her deeply and want to be with her but I don't know if I should just take this as a sign and move on with my life.
