Reading your threads, it sounds like you are in a much better place emotionally. I'm glad you are able to go around your ex and not be drawn in. But just some advice, allow her a chance to figure out her life now, without you as an option.
Can you paint the room? Yes I understand it's for your daughter, but sooner rather than later, you STBXW will have to learn how to figure out situations without you.
Figure out a way to inform her you are no longer an option, it's best if she start learning how to find a contracting company or person, or she can paint herself to do things in HER life. This is the life she chose. A life without you! Allow her to live that life without you. If you ok with being friends with her find. Friends doesn't mean ACCESS.
You are no longer her husband and placing yourself in that role in any fashion doesn't allow both of you to grow.
I'm glad you are deciding to take your time with this new lady, being high value doesn't stop you from hurting others or from getting hurt.
I also agree with getting out and meeting people and moving forward with your life, it doesn't help to be a hermit.
I spent a lot of time in behavioral heath for all kind of reasons before COVID, it helped. My counselor was a cool dude.
Keep moving forward and posting.
