Dating after divorce not going well...

I've been separated for two years now but still don't feel ready to date and I'm not sure how to get there.

I thought I was ready when I recently met someone I was excited about, but I found myself never able to fully dive in or commit because I still feel too tied to my ex mentally. Like I still can't quite imagine building a life with anyone else, or getting excited about a future with them if that makes sense.

I live on my own and am happy with my life, but I would love to move on and build something with someone again. How did you all mentally get there?
