I'm actually happy for you, dude. I know just what you mean about having found your peace and realizing that it's more valuable to you than chasing after hope. I have made the same decision myself and I can tell you, years later....it is and was the right one. Zero regrets.
There's too much pressure on people to date. It's time we recognize that not everyone is wired well for a romantic relationship. And there's nothing in the world wrong with that.
Focus on your kids and your birth family an friend relationships. You want to avoid isolation and a negative emotional spiral.
I wish you the best going forward man.
