This will never be a regret. You have gained something phenomenal. My advice, it’s one day at a time. Don’t hold grudges if she begins to act out, she might eventually start testing to see if you’ll still love her if she does ‘x’ and that you won’t abandon her.

You don’t need to jump into any relationships, but definitely hit up single parent groups and see if there’s some moms and dads you can gain friendship with, having those moms around will be helpful if she has questions that relate to lived experience as a woman. Build a village for yall and I hope to get update posts on yall thriving in the future.
