Actually, you do want a crash, but I don't think it will be coming this quickly.
Ron, this is a long process. If your W is truly MLC, don't even try and look to the future. Take it one day at a time.
I am going to be very blunt here, please do not take offense. But IMHO you are a little controlling. Remember, right now, you cannot do a dam thing for your W. You have to let her be. If she wants to smoke five packs a day, there is nothing you can do. You are helpless right now, and if you continue to try and tell her what is best, or worse, you will send her right out the door.
Back way off. WAY OFF. Be kind, be cordial, and leave her alone. Get your your interests. If you like to do something, do it. Let her do her thing right now. Trust me, the more space you give her, the better off you will be. But, this is not an overnight fix. You are looking at months, if not years. You need to make sure you are in this without any pressure, without any expectations. 0, zip, nada, no expectations. Just because you have one good conversation, that is not going to mean that everything is going well, the next day could be hell.
This is one of the most difficult situations you will EVER face. Pray alot, find your inner peace, and do whatever you need to do to improve yourself. We all can improve. And at the end of the day, do it for you, not for your W. You have to do it because regardless of the outcome, you want to be a better man.
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
