I'm 26, and I'm wondering if I made the right choice.

I'm John, 26, and I've been in a situationship with a girl, 24, for nearly a year. She ended her relationship with her boyfriend last year to be with me, stating she had lost feelings for him, and after a month, she chose to pursue things with me. We've been acting like a couple since then, though we never officially defined our relationship. Recently, she's become distant, ignoring me for almost two weeks and pulling away from intimacy, saying she's too exhausted from work and needing to support her family. I tried to talk about our situation, but she declined. Out of frustration, I decided to end things and returned her belongings. She later sent me a lengthy message explaining that she isn't ready to commit, wants to focus on herself, and is afraid she won't be a good partner. Now I'm questioning my decision. I still have feelings for her and want to be with her, but I'm uncertain if she's truly ready for a relationship after almost a year without a label. Should I block her on social media to help myself move on, or did I make the right choice in breaking up?
