How can I heal after this painful divorce?

Assalamualaikum. I recently discovered that my husband was unfaithful with another woman. I had my suspicions, but having them confirmed - and not by him confessing but by friends who were on the call while he was flirting - crushed me. There were even video clips, so this isn't just rumor. Because of that betrayal, I pushed for divorce; adultery is a boundary I could not accept. Right now I'm a mix of feelings. Part of me feels relieved to finally have clarity and to be free from his blame, projection, and lies. But underneath I feel lost. He was the one who guided me to Islam and helped me grow closer to Allah (S.W.T), so it's painful to see this happen. I always respected him and trusted him because he presented himself as a man of faith. Astaghfirullah, I never expected he'd cross this line. I'm angry at being misled and frustrated because he used to tell me I wasn't religious enough, that I needed to learn how to be a proper Muslim wife, and that I was too emotional. Now it all feels hypocritical. I also hate how attached I still am - how I can't just let go of someone who caused me so much hurt. I miss his presence and find myself wanting to tell him about my day. How do I move forward? How do I stop missing him and heal when my heart feels so soft? Please make dua for me and share any advice or practical steps that helped you or someone you know recover after a painful betrayal and divorce.
