Ex best friend sent me a message

I was best friends with a girl 3 years ago but I ended it because she was manipulative, mean, and so many negative things that I just got sick of. I was always there for her and I never treated her badly yet she was always so hurful.

She messaged me yesterday apologizing and in a nutshell she said that she wishes things hadn’t ended the way they did and that she’s truly sorry. She mentioned how she’s changed and matured since high school. She asked if I could forgive her and hopefully would like to be friends again. Her message was fairly long.

I responded within the next day and I told her that it was in the past and that we’ve both matured and that I’m not angry with her. I said that I’d like to start fresh again and be adults about it. I even apologized for the way I ended the friendship. My message to her was well thought out, pretty lengthy, and all together thoughtful and kind.

I saw that she’s read the message but she hasn’t responded to me with anything at all. I seriously doubt that she’s terribly busy and I now feel stupid for responding to her so promptly. What does this seem like? Is she not responding to me to try and “get back” at me or something? I just feel like she’s now ignoring me which really bothers me since I replied in such a positve and mature manner.

I feel like I shouldn’t have even bothered with responding to her. I got my hopes up thinking that she’s maybe changed and that we can give our friendship another chance. I’ve been perfectly fine and happy without her as a friend but I thought it would be nice to give it another try. So much for hoping for the best and trying to be postive about this little situation.
