Feeling Lost After Our Breakup - Need Dua and Advice

Assalamu alaikum. I broke up a few days ago after being in a relationship for about 2.5 years. It was on and off at times - we split before because we were immature at first, and later I decided to step back for the sake of Allah, but we kept getting back together. Each time we thought it wasn’t really over and that we would return to each other and eventually marry. This time was different. He was the one who ended it, which he never did before, and he said he won’t come back. The strange part is that on Monday I prayed asking Allah to guide me and to choose what’s best for me, and that same night he asked for a break - something he wouldn’t normally do because he doesn’t really believe in breaks. We didn’t speak for a day or two, then we talked Wednesday night. On Thursday I was ready to leave him for the sake of Allah, thinking we’d still marry later. But before I could, he ended things. He gave a reason that doesn’t sit right with me, and later on a call he said it wasn’t just that reason - something in his mind just clicked. He told me he won’t come back and that I should find another man to marry, but he said he still loves me. I’m confused. He was everything I had prayed for: good character, good family, and he brought me closer to my deen. I used to ask Allah for someone like him in my duas - while fasting, in the rain, while traveling. I try to remind myself that Allah may have separated us for my protection and for what’s best, but I keep thinking: if we weren’t meant to be, why did he seem to guide me to ask for him? Why did Allah give me signs when I asked? I’m shattered and it’s affecting me a lot. I’ll be 22 in a month, and honestly I would have married as soon as possible if things had worked out. Please make dua for me and share any advice on how to heal and trust Allah’s plan. JazakAllah khair.
