Should I respond to her?

I started casually seeing this girl from a dating app, I made it very clear I wasn’t looking for anything serious and we agreed to just hang out, watch movies and hook up. We agreed to let each other know if we slept with someone else. After a few times, I found out that it wasn’t going to work out, she has severe depression and was looking for more from me. She had told me about some of the guys she was talking to, and when she asked me about the people I was talking to, she got upset and asked why I would be talking to someone else and if we should stop.

This was all too much for me, this wasn’t a healthy relationship for either of us and I began to distance myself and eventually told her that I didn’t think I could continue this, for a lot of personal reasons. She said ok, I said I was sorry and that was that.

Today, she texted me asking if she should delete the list of movies we were going to watch or did I just not want to see her ever again. I had a very stressful day and wasn’t sure how to respond and I didn’t for most of the day because time got away from me. She sent a follow up saying “sorry for bothering you. I’ll delete it. Hope you are doing better” and I honestly don’t know what to say or if I should even say anything at this point.

It’s important to note that we had only been casually seeing each other for about a month and hung out about 4 times.
