When your husband hits that midlife crisis, do not give up hope! Save your Marriage! One thing you have to remember is, all men are different. Just because you know other men do not act that way, does not mean he isn't going through a rough patch.
He may put the blame on you, it could be his job, or possibly a death. Whatever the reason, he will only know! Try to be as patient as you can, do normal day to day routines. I know it can be very difficult to make it past the mean words spoken,
Please do not take it personally. You're the one beside him, so he will put it on you. It time, you will see you are not the problem. Things will get better for you both!
