feeling devastated after breakup

I was dating this girl until a few weeks ago when she broke up with me. we only dated a month (didn't put labels on it), but we had been very good friends for several months before. now we're not speaking (we decided we could both use some distance) and I'm heartbroken. I miss her so much, I know I should be moving on but I can't. I'm not sure if I could settle for being just friends after this but it might be better than not talking at all

she said the reason she wanted to stop dating was that she had commitment issues and wasn't ready for a serious relationship. we agreed to start out slow when we first started dating but at some point she must have felt something that made her doubt this? I know she was very into me and also had feelings (maybe even now still), so I was shocked when all of a sudden she decided to break it off

now I'm waiting for her to reach out (I don't want to do it myself as she was clear she needed time) but even I'm not sure at times if it would be okay for us to talk again. I'm afraid that she has moved on already while I still have feelings for her. but I'm also scared she just wouldn't want to talk again... I am completely stuck and feel very depressed over this whole thing, it just shocks me how suddenly everything has changed. I'm trying to keep busy but barely anything can distract me from the pain

thank you for your patience with this and any advice you might have for me!
