Will Allah forgive us if we don't repent?

I've known my fiancée since 2025, and insha'Allah we're hoping to get married in March 2027, alhamdulillah. She used to have a lifestyle that wasn't aligned with Islamic values until 2024, and that was something I struggled to accept at times. But honestly, it doesn't weigh heavily on my mind anymore because she has put in a lot of effort to change, and alhamdulillah, we're mostly on the same path now. Still, one thing that lingers in my thoughts is that she seems 'at peace' with her past. Yes, she has transformed completely, and I firmly believe Allah is the Most Merciful and forgiving. However, she doesn't express deep remorse over those previous actions and hasn't specifically sought forgiveness for them. I'm content with her current state, but I often ponder whether forgiveness is granted even without direct repentance. Insha'Allah, I sincerely wish for both of us to attain Jannah someday-though I'm not in any position to judge if we will. I hope you understand my concern. Jazakallah khair.
