Men love a good challenge. They want what's hard to get. With everything you're doing that feels counter-intuitive, think of it like this: You're not doing it to get a reaction out of him (that's contolling), and you're not doing it to be mean and catty (that would backfire); instead, you're doing it to create an air of mystery around yourself. Your H NEEDS to think - and begin to FEEL - he might lose you.
While you're ignoring many of his texts (my personal phililosophy was to respond only to asked questions, and even then I'd take my precious time responding), make some plans to go out on the town with some girlfriends. Don't tell your H where you're going. Buy a new outfit, a new perfume, some new jewelry. Be neighborly-friendly to your H, but not flirty. Be distant. Mysterious. If he asks where you're going, smile and say, "Out with friends!" If he asks what time you'll be home, reply: "Probably late. Don't wait up!" And walk out. This will make his head spin, AND it'll make YOU feel confident and powerful. And we need you to start feeling those things again. You may not feel like going out. Force yourself to. And don't tell H with whom you'll be. Also, don't tell him anymore of what you know about his A. No more specifics. In fact, don't talk to him at all about the A, your relationship, etc.
