Is this how its supposed to be?

It is highly possible for men to shut down when stressed. I know a lot of people believe that mens anatomy works whenever and however. That is not true. My husband doesn't respond at all when we have been arguing or even when there is money on his mind. There also are times he physically can't respond to me because he is drained. If he isn't committed you will know that though. One sign is the address change. If you want to save the relationship quickly try to spice it up. Don't nag and don't get all neurotic. If he wants to go he will. Are there any other signs other than the address change that would leave you to believe he isn't interested in you?
