Struggling as a Revert - Feeling Heartbroken, Need Advice

Assalamu alaikum, I hope it’s okay to share something personal without being judged. I’m a revert still learning Islam, and right now I feel really lost, heartbroken, and alone on this path. I don’t have any Muslim friends yet, so I’m reaching out for some guidance. I recently ended a relationship with a Muslim man I truly cared about. Through him I found the beauty of Islam and eventually embraced the faith, Alhamdulillah. We had many good times, but also struggles: cultural differences, expectations, long distance, and my own anxiety and fear. As a revert, adjusting to a new way of life and all the changes was hard, and I found it difficult to balance everything. In the end I panicked and ended the relationship because I felt overwhelmed, scared, and confused. He has asked for no contact now. I respect that, but I’m devastated. I feel guilty, heartbroken, and unsure if I acted out of fear or if I made the right decision. I miss his support and the way he helped me in my faith, and since we stopped speaking I’ve felt very alone on my journey to Islam. I can’t shake the feeling that Allah brought him into my life for a reason, to guide me to Islam, and I worry I’ve ruined something that was meant to be. I know being in a relationship before marriage isn’t halal and that I didn’t handle things perfectly, but I’m learning and trying my best as a new Muslim. Since the breakup I’ve started praying more regularly, making dua, and trying to draw closer to Allah instead of returning to old habits. Salaah brings me peace, but the sadness, loneliness, and guilt still feel heavy. I would really appreciate Islamic advice on coping with heartbreak, how to tell if ending it was a mistake or if it wasn’t meant to be, and how to deal with feeling lost and alone as a new Muslim without a support network. Any guidance or words of wisdom would mean a lot. JazakAllah khair.
