It's very perceptive of you to have noted the premature sex, OP, and particularly the playful but extended restraint. It was also, as you know, wisely self-protective to use Clare's Law and to explore your reactions on here. You're not as daft as you think!
I like the term used above, compliance testing. There can be a familiar dynamic for those of us who've been conditioned to abuse, a sense of "This is a game I know". It can feel pretty great, like finding a well-matched dance partner.
For me, the early-stage challenges were fun. I'm slightly horrified to look back at myself choosing a battle of wills as an essential relationship component. It goes without saying that, much as I may have won a battle here and there, I was opting into a war. What I wanted was a mutually supportive, kind, equitable relationship. But I was compliant with war games, so that's what I got.
I have some faith that you'll walk off the battlefield this time! You'll only get a kind, supportive relationship if that's what you choose.
