I want to know if it will be permissible to marry a girl whom I committed zina with and told Allāh

There is this girl whom I was once in a ḥarām relationship with. Unfortunately, we committed zina multiple times. We cut each other off in 2021, and I sincerely repented to Allāh for my mistakes. I also told her that “I swear to Allāh that I will never be with her again”. Unfortunately, I also said this out of anger and not in a good mental state. Presently, me and this girl have been in contact again (not dating at all) and I was wondering, would it be permissible to marry this woman? I only ask because she exhibits exceptional qualities that a good mother/wife exhibit, and she also treats her family very well. She is also in a good mental state as well.
