Destiny, Have you ever just sat and listened to what he has to say w/o offering up your opinion? Maybe you need to step back a little and treat him as a friend who just wants someone to listen and not offer up advice. He's not looking for you to fix things...he just wants to be able to talk. If you don't step back and keep your expectations at zero, the man is going to turn to another woman. It may not even be the same one as before.
I understand your concern about the porn...Do you question him about everything that he does or doesn't do? If so, that could also be why he's not talking to you. Remember...you are not his mother and you do not want him to look at you in that manner either.
His crisis is about him and him only and he needs to find himself and figure out what it is he wants, where he wants to go w/his life, etc. Your journey began the same day as his. Your journey puts you on a different path and that path is one that is for your self rediscovery. Destiny, please stop expecting this man to snap out of it...it takes a lot of time. If you really want off the train of mlc, then step off, but I warn you, once you open up that car door, there is no telling where or when that train will return to the station and who will be on it.
You need to decide are you on or off that train? If you are going to remain on the train, then you need to turn it over to God and allow him to do the necessary work to heal your husband. You can't do it because you didn't break him. You can only fix yourself...so are you with us or have you had enough? If you are w/us, then you better start digging deeper within yourself for more patience because that is what it is going to take to get through this. Just remember, the more you push, the harder they will pull away from you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
