I have been reading your threads all the way back and if you really want to fix this you need to stop trying to fix her. You blame her for it all but honestly this last thread I am sure from reading past threads that she was on the receiving end of your rage also. You start this thread as if you were the perfect husband and never did to her what she finally snapped here doing.
I am very abrupt at times but feel someone can't sugar coat something and expect things to turn around. Its not going to and it will get worse as it goes on. I lived it. Its not your wife and her being nuts or crazy. Its the dynamics of your marraige and both of you contributed to it. Your just trying to find a way to dig her under since your upset she is not acting like you want her to.
You are too much into trying to change her into your perfect world instead of focusing on yourself and what you can change. You can't do that. It will only cause tension and arguements. She is human, remember? Faults and all. And you seem to carry on and go at her when she clearly doesn't want to talk about certain things till she can't take it no more.
You can't change her again. Remember that. Only you can change. You can't make her act like you want, only you can set the example for it and pray she will follow. If you are true to your word you will not try to undermine her but work with her and acept her shortcomings and such.
Do you appreciate she makes your lunch or do you take it for granted that she must do it? Of course she is going to deal with the kids cause they are hers also.
Not even 8 hours later you have a different opinion on her. You are focusing on changing her and if she isn't what you want her to be you automatically want to call it off again. Do you want this marraige or not? Your either in it or not. Focus on you and how you can become a better parent and husband and try your best to make her happy. Not elaborate on her faults and what you dislike about her. She will automatically put up a defensive front and an arguement will ensue. Tell her what is good about her instead and leave the rest out. Don't over analyze things. Try it out for a couple weeks and see how she treats you then. Its really hard to change habits that we are so used to doing. As time goes by and you figure what works and what doesn't, it will steer you more toward acceptance of who she is. This is the true person you married. You can't change it and need to accept her for who she is. Not try to mold her into what you want her to be.
