She added me back?

I (F, 23) told the girl (22) who I’ve been going out with for a few weeks that I couldn’t give her the relationship she deserves - for various reasons all having to do with myself personally and not her, she’s an amazing, beautiful girl, and I told her I’d love to still be friends if she wanted that too - she said she doesn’t want to however.

She of course was upset and disappointed and once the conversation was over she left and immediately unadded me on everything, didn’t block me though.

Then the next day she re-added me back on Snapchat. I reached out to her to thank her for adding me back again, and that I’ll give her space. She never responded and left me on open.

I’m just curious on maybe what are other people’s thoughts? Like why would she re-add me? This is my first time going out with a girl, and maturity wise I’d have a different, calmer reaction, so I’d just appreciate other opinions.

Thanks!
