Reached out after almost two years.

Me and her have been friends throughout highschool like really close spend every day together friends. she was a bitch to everyone except me and then We moved in together two years ago and it only lasted a few month because it did not Go well. She started being a bitch to me too. We did not mesh well living together. I reached out to her because I’d been dreaming about her all the time the last few months. I started it w a joke and we just kept laughing it’s been a week now and we have hung out twice. She still has all the pictures of me up on her instagram and all the art I made for her in her room. We have both recognized that we were in bad mental health spaces when living together and have apologized. Is this something I can salvage and have my close friend back or is it too good to be true?
