(I wish I was one of those people who always knew what to say to make everything sound like it is going to be ok. But I am not, I have seen too much to believe that kind of thing.) I've been keeping up with your posts over the last few days and What I can say is.....
As her wife it is just as much on you to help her as it is for her to find herself. If she is unwilling to accept your help that is one thing, but do not withhold it if she needs it.
Also,
If you HONESTLY feel the way you say you do, about not being in a marriage, then you need to sit her down and tell her that. She either needs to help you work on the relationship or you need to explore other options. Maybe some time apart would be helpful to the both of you. A relationship, of any kind, is not supposed to be one-sided. It is supposed to be a partnership, not always easy I know but if you are the only one committed to making it work it wont. Be honest with her. Tell her how you are feeling. Have her help you decide if it is worth working through. (I know, I know, we SO's are supposed to be supportive, stand by through anything kind of people, but I feel that if it gets to the point of potentially loosing yourself in the relationship then it is time to step back and look at it from a more 'realistic' perspective.) There is nothing wrong with doing what is right for YOU. (not meaning to be negative or pessimistic, just my opinion)
Also, may I ask what kind of expectations you hold her to that bother her so much? And is she actively seeking employment or just putting out the minimal applications in order to collect unemployment?
