What I've done to change that behavior in the past week (so far): connecting with my girlfriends (and their girlfriends!) so I always have things to do. Acceptance. Giving him total space to drink, smoke, withdraw, ignore me, sulk, whatever. Pray. Love him from from a distance and not ask him anything personal, just behave kindly. Not questioning anything I normally would. Joining back up with my spiritual program to plug back into some real 'power' again.
What I've done for him: apologized, tried to make him feel comfortable without having to talk when he does come into the house, saying hello and being pleasant, not icing him out or throwing bad energy at the situation or him, doing the dishes and laundry, hiking w the dogs. (That's kind of for me though). I guess I'm working on being the kind of wife he'd want to be around.
Bestgal, these are all great things. But I do want to be clear that we are talking about behavioral problems for you. Don't get me wrong, everyone would like to come home and have the laundry and dishes done. But this isn't about doing nice things for him to try and win him back. It is about changing who you are, not fundamentally but maybe bad habits and behavioral patterns that you have picked up. It is good that you are not throwing bad energy at him. Why do you think that you have thrown bad energy at him in the past? What causes you to do that. I do agree with the 'fake it until you make it' mentality as it pertains to happiness. But I'm not sure you should apply that to the behavioral concepts, IMHO. I suppose that is one way of learning, or unlearning a behavior though. Just make sure that you are doing those things for you. Whatever causes you to throw that bad energy around or get riled up, take some time and try and figure out why you act that way. Maybe an IC, maybe you already know. But if you don't get to the root of it, you will just end up in the same place 6 months from now, whether he comes back or not. This is a chance for you to improve yourself, for YOU and hopefully in the process let him see that and kick himself for ever thinking of leaving. Take it.
