I have been married for 18 years and I will be the first to say that it has been a challenge there were times that we both thought it would be better if we were divorced but the reality of life is that marriage is one of the best relationships we can have, and all though it has some challenges along the way does not mean to just give up.

Some of the challenges we think we are having with our spouse can sometimes reveal something that we need to work on within ourselves.
There are several things you can do to assist in moving forward beginning with realizing that you can't change her but you can acknowledge how she feels apologize and advise how you will do things differently in building trust. The responsibility of a man is great and can be challenging when his spouse is in a bad spot but remember it is only for a moment and your fight can make or break her.
As a husband, you should focus on building your wife up. if you know/think she has no self value it should be important for you to cover her in that area.
She needs to talk to someone about her feelings and not someone who will make it okay for her to continue the way she is going but in a way that will make her better and move on to see that you are the great man that she fell in love with.

If you have any more questions please give me a call.
