Leaving a close friendship for the sake of Allah: A tough but necessary step

As-salamu alaykum everyone. I've been working hard to delete all our chats and let go of the memories of a sister who was once my classmate. She really helped me a lot-with my career, with understanding my Deen better, and even teaching me how to control my anger and make sincere dua. She gave me hope, but because of her kindness, I ended up putting too much emotional pressure on her. I thanked her excessively and offered Islamic advice way too often, crossing into personal territory without anything haram happening. I realized this was a grey area, and Allah tested me with a difficult separation. It was especially hard because it felt one-sided; I kept pushing to marry her, trying to force my help on her, and offering gifts and food she mostly refused. May Allah reward her for all her good efforts, protect her, and grant her Jannah. I feel some peace knowing she's safe now. I take full responsibility. It turned into a situation of emotional strain, and someone else had to step in to help me distance myself completely. Now I'm deleting everything to heal from this loss and move on, which is a step I'm taking for Allah's sake to overcome these strong feelings. I feel guilty about my actions. I've heard from some that she's forgiven me, but others said she felt really scared and uneasy in class-may Allah have mercy on her and keep her safe. I didn't realize my overbearing behavior was causing her so much stress; she stayed quiet for months before finally speaking up when I crossed boundaries again. Q1: I want to move forward, but I can't apologize to her directly since we're no longer in contact. When we wrong someone, we need to seek forgiveness from both Allah and the person. How do I handle this so I'm right with Allah? Q2: For those who've made sacrifices for Allah's sake, did you get over the loss? Did Allah bless you with a good marriage or make your life easier? When did things get better? Q3: Compared to that past connection, was the person you later met more aligned with your values, purer in character, and more supportive in helping you please Allah? I seek Allah's forgiveness and hope to learn from this to avoid even nearing zina. Even without physical actions, I felt the harmful effects, and it was my fault for trying to justify it as halal. An emotional bond doesn't excuse my mistakes-I've faced the consequences. Jazakum Allahu khayran.
