I like the books you have listed. I have the singles go to a website called Amazing Marriage ,By Rabbi Pamensky. He offers some free downloads. I have an email with his downloads on it.
I also like “For Men Only” and "For Women Only"by Feldhahn. It is not jewish. 99% psychology.This author interviewed 1000 singles. She also had them fill out a survey. Her tone is respectful ,caring and simple, not complicated psychobabble. A few words here and there not for us. It is from 2004. used copies everywhere. When the singles understand the opposite genders thinking , the dating is more productive. Not so much game playing.
Everyone knows the book the "The Five Love Languages"By Gary Chapman, there is a version for singles. The first chapter alone is life changing.
Another book is "All the Good ones aren’t taken"by Debbie Magids. This author outlines 8 types of daters and how each type keeps them single. When a single can see their pattern, that gives them the opportunity to control the outcome.
