Surrendering My Heart to Allah: How to Let Go of Someone I Love While Keeping Them in My Duas

Assalamu alaikum, everyone. I'm really struggling with something and could use some advice from the community. I've developed strong feelings for a woman and my intention is to marry her. In the past, our interactions were not within halal boundaries, but for the sake of Allah, I've stopped all communication with her to avoid further sin. Every night in tahajjud and during my daily prayers, I make dua asking Allah to reunite us if it's good for me, or to bless her with goodness if she isn't meant to be my naseeb. I trust completely that Allah is Al-Qadir and knows what's best. My confusion is this: how do I truly surrender this situation and this person to Allah while still making dua for her? And how do I go about my daily life without constantly worrying about whether she's moving on or talking to other potential suitors, when I'm still praying for her every night?
