How to Navigate Dating After a Toxic Marriage

I'm navigating dating again after a very toxic marriage to an actual narcissist. I've been in a relationship for about six months, taking things slowly and keeping a close eye out for old patterns or red flags. My partner is super thoughtful, generous, kind, affectionate but he is also showing some co-dependent traits. He's very much a fixer helper type and a little insecure, worried that small things will make me not like him anymore. If you want to go on this adventure, if whatever, it's fine as long as you both come to the table and discuss it and talk about it.
