So story is I had been seeing this girl about twice a week for two months, and it was going really great.

Obviously not.

We got along well, and it seemed like finally some good stuff was happening for me in that department - we even had set up a slack team so we could talk during the work day, and did all the time.

What is a slack team?

Then, out of the blue, a day after going out, she texts me to say that while she "really loves hanging out with me", and that we "get along so well", that she "isn't emotionally on my level", and thinks we should stop seeing each other.

She's isn't emotionally ready for a commitment to you but I bet someone else caught her eye.

I'm pretty confused, and kind of broken up about it. I've dated a lot of people in the past few months, and never really hit it off with someone like that. I told her I understand, and thanked her for her honesty, and then stopped contacting her entirely, deleted the slack team (this was at the beginning of the week).

My man. I'm proud of you.

I know that it's best just to forget about it, and move on, but I just want to know if there's any hope of salvaging something.

There's not. Move on and you'll be a better man / happier man for it.
