Forgetting Past Haram Relationships in a Halal Marriage?

Assalamu alaikum everyone, I've been thinking about something and would love to hear your thoughts. This is especially for reverts: Imagine before embracing Islam, you were in a serious, long-term relationship where you deeply loved someone and even imagined a future together, but it ended. Then, after reverting, you entered into a blessed halal marriage. Has anyone experienced this? I understand we can't completely erase memories since every person teaches us something, but in your halal marriage, do you feel a deeper, more fulfilling love for your spouse? Do thoughts of that past relationship come to mind often, and if so, how? Do you ever reflect and think maybe it wasn't true love? I'm really curious to know how you feel when those memories surface.
