Reference sections and other suggested readings from the back of books I enjoyed. This is mostly for more non-fiction books but its helpful to see what the author recommends. I have often found books I love from his method and the really good ones get recommended from multiple related books. Especially if its for some interested that is new to you.
This will depend on how long you have been dating someone. On a first or second date or whenever it is first mentioned don’t drop everything at once. Say something simple or innocuous that is true but not a full detail. Say something like “My family and I are not close because we don’t have the same values” or “My family and I are not close because they drive me a little nuts and we don’t have to get into it now” or “I am moving towards non-contact with my family”. What you want to show is that early in the relationships you can show good judgement to whoever you are dating and don’t trauma dump about your crazy family all at once.
As you date someone more you can show who you are. You can demonstrate through your actions that are a normal person and don’t follow your family dynamics. This also shows that you understand what is and what is not appropriate for first dates. From there slowly roll it out doing a high level summary like you gave above. From there just tell stories as they seem appropriate. So its going to be a full disclosure but won’t be full disclosure right away
My wife has a pretty crazy mom and dad. She did something similar where she first talked through their contentious divorce and then more details as we were together. Her story is a little different because her family isn’t as nuts as yours and she didn’t realize how toxic they were until she did lots of therapy while we were dating. So we are now reframing her quirky childhood stories and two crazy people making each other as miserable as possible and the trauma that caused. So a slow roll is what is needed.
Also note we are all messed up so you are not the only one.
