I forgot to say: a great book on this topic is "The Passion Trap" by Dean Delis. I think I first heard about it in this forum somewhere.
Really an amazing book; spends more time on the mental states of the Pursuer/Distancer than Solo Partner, as I remember (I could be wrong), rather than strategies, although it does contain strategies for both.
It focuses on helping the Distancer understand their need for distance and deal with it. It also describes how the Pursuer might understand why they pursue and how to stop it. Not a book a clueless Distancer is likely to read, unfortunately.
