You are going down cheeseless tunnels. Try to remember that you wife is repulsed by you right now. How would you react if someone that you are repulsed by kept kissing your head or trying to have R talks with you? It would repulse you even more. The changes that you make should reverse that. You can be kind but allof. Mysterious even. Play your cards tight and act as if you could take or leave her as well. Ever hear of the Hawthorne Effect? Subtle changes make a difference, even unconsciously.
Your W has filed. As far as she's concerned, every effort made by you to win her back will have her digging her heels in harder. How do you get a horse on a trailer? You don't push it on, that just causes them to resist. You coax them on so that getting in becomes their idea.
