Games are the most fun when everyone involved knows they're playing, and when to quit.
You do not have as much information as you could. Talk to him about it. Phrase it as "I feel this" not "you do this", I'm sure you know about that sorta thing. Frame it differently, he may agree with it, ie "It's a lot more fun when there's a bit of back and forth rather than someone just agreeing with you" vs "the thrill of the chase is a mind game and i don't like it".
If you feel it is unethical to do that, stop. You may be able to reframe the issue to make it not-unethical, but that does not mean it will be as good as it can be. To do something you feel is unethical for the sake of a relationship sounds like it would hurt your relationship with yourself.
That said, he's not your only option, there's other guys out there. I abhore mind games and so does my gf and we've done well by being honest, open and forthcoming. You may have similar luck in finding someone who is open and honest.
