For abuse awareness, I always recommend Lundy Bancroft's excellent book "Why Does He Do That?" - free PDF is available online. Gamechanger.
The power and control wheels (Duluth model etc) illustrating the various tactics used in coercive control are also extremely helpful.
As for early dating warning signs of an abuser, Dr. Dina McMillan's UNMASKING THE ABUSER Podcast is so good.
Episode 9, S1 E9 (29 May 2020) "Outrunning the Beast" in particular really resonated with me:
"Learning the tactics of manipulation used by Abusers to entice new partners is fantastic! But is that enough to keep you safe in Real Life if (or when) you're targeted by one? In this Episode we discuss strategies you can use to both accurately identify a potential Abuser and get away as quickly as possible. We even discuss how to keep from mislabeling someone as an Abuser because you defined them with too little information."

I’m on episode 5 of the podcast and I’m finding it very informative. I’ve already read Bancroft’s book.
Thanks for the recommendation!
