Have you talked to her openly about the way that you have been feeling? It my help her to better understand since woman like to talk about things and if you talk to her in an assertive way and from your perspective (try saying things like "from my point of view..." or "I feel..." so as to her not feel attacked by you and for you to let her know that you are experiencing such feelings and emotions of your own).
How about also tackling some couple therapy? That's a way for both to talk while having a mediator and reconstructing the relationship you have while are the same time each working at your individual obstacles.
You could try first finding support by yourself and then if needed suggesting her about couple therapy but if you truly value your relationship try to be more open to her; remember woman like to talk and to listen and if she's your wife and supports you for sure she'll be there to support you.
Best wishes for you and your family...
