Choosing Allah's Path by Letting Go of a Close Friendship

I've recently decided to distance myself from my closest friend for the sake of Allah, and it's honestly breaking my heart. If you have a moment, please read on because I feel completely adrift right now, and I apologize if this gets a bit lengthy. We first met back in early 2024 during an internship and clicked immediately. But about three months later, they moved to another country, and we stayed in touch long-distance. By the year's end, it was clear we'd developed strong feelings for each other, and we kept talking despite the situation. I was young and naive, and I got attached really quickly. A few months after that, they wanted to end the romantic aspect of our relationship to follow what's halal, believing it wasn't right to let our feelings grow stronger outside proper boundaries. At the time, I was too attached and scared, so I said no, thinking they might just be trying to push me away. It turned into a big argument that left us both a bit shaken, and we ended up trying to patch things up and continue anyway. We went on for another full year. During that time, I started university in a different city, and a lot of arguments started popping up. By the end of my first semester, we were both completely drained. They visited, we met, things felt amazing again, but once we went back to long-distance, the fights resurfaced. I started pulling away to protect myself, trying to limit our conversations. Then came Ramadan this year. I'd already been working on strengthening my relationship with Allah for a while, but this month I really gave it my all. I've never felt closer to Him. I prayed a lot about our situation, asking if it could be good for both of us without causing harm, and if so, to let it happen in the halal way. My mindset began to shift toward what they had felt from the start. I thought if nothing else was improving between us, that might be a sign that we needed to do things properly now. I made dua, asking Allah to take control of the situation because He knows best. After that, I put my full trust in Him and stopped interfering-no more initiating texts or conversations. They noticed, and we talked about it, agreeing it was for the best, though it was still tough for both of us, with occasional messages here and there. After a stretch of not talking much, we had a serious chat last night. They expressed feeling it was unfair since I'd initially resisted their attempt to do things the halal way and now I was doing the same. I felt terrible and apologized sincerely, explaining my thought process over the past months. I admitted I wish I'd agreed when they first suggested it and that I regret letting things go on like they did. In the end, I promised that I'll still be here when the time is right, InshaAllah, and apologized again. They said they were upset but proud of me for drawing closer to Allah and recognizing we needed to do things properly. After that, we removed each other from everywhere, which has been really painful to deal with. I'm not sure if it's just because it's so fresh, but I'm overwhelmed with fear and doubt now. I feel awful for realizing this so late and for having made them compromise their beliefs at first. I'm feeling so lost. What if Allah replaces them with someone else? I don't want that. I know He knows what's best for me, but I want Him to make them the best for me. The uncertainty of not knowing how long I'll have to wait or what might happen in the meantime is really scary. I'm trying to remind myself that this could be my duas being answered, bringing us together in a halal way, but the lack of clarity is testing my iman. Any advice would mean the world. Please help a sister out, jazakallah khairan.
