Fellow sister seeking help to move on from a past relationship

As-salamu alaykum, my dear brothers and sisters 💚 I need to open up about something that's been weighing on my heart, and I sincerely ask for your support and advice. I embraced Islam two years ago, alhamdulillah. For about three years, I've known someone, but I want to clarify that my reversion was not because of him. I was already drawn to the deen even before we met, and my decision to become Muslim was my own, for the sake of Allah. During my time as a Muslimah, I was involved in a relationship with him that was not permissible. I knew from the start that his family strongly preferred him to marry within their own community. We both understood that an arranged marriage was likely in his future, though I admit I held onto some hope that things might change. He actually proposed to me in secret several times-about three-but we never acted on it because we knew that hiding a marriage like that is wrong and goes against Islamic teachings. Then, at the end of the last year, I discovered through social media that he had already performed his nikah. I found out from a post shared by his brother, which he then reposted. There was no discussion, no heads-up-nothing. When I asked him about it, he said he didn't know what to say and that he tends to avoid difficult conversations. The hardest part is that he's still trying to keep in touch. He claims he only agreed to the marriage because he heard positive things about the sister, that he doesn't really know her, and even mentioned she isn't his type. At one point, he even suggested marrying me... after his nikah was already complete. I know this is not right. I know this path is not pleasing to Allah. I've been making du'a constantly, asking Allah to remove him from my life if he isn't good for my dunya and akhirah, but I'm really struggling. My feelings for him are still strong, and I find it so difficult to muster the willpower to cut ties completely. I read the Qur'an, I pray, I strive-but I feel trapped between what I know is halal and what my heart desires. Has anyone else experienced something similar? How did you find the strength to let go and choose what is right over what your emotions were pulling you toward? Please keep me in your prayers. I truly want to improve and seek Allah's pleasure. Jazakum Allahu khayran 🤍
