I am sorry to hear you are struggling in your marriage.
It seems like your husband is beginning to pick up on your anger, but he seems to be at a loss as to what is causing it.
He seems to be under a stress " I don't want to deal with problems, I have enough problems in my life" One way to start a dialogue is to allow him to talk about his problems so he can let some of his fristration go..it might also provide you with some insight as to where he is coming from.
Walking away is not really a solution, unless you think you are going to lose your temper or if he is getting verbally abusive. If you can hear him out when he is expressing anger in a reasonable way, it will demonstrate your investment in him.I am assuming you want to stay in the marriage, let me know if I am incorrect.
If you need for him to "hear" your side of the story, you might consider wrting it in a letter. It will help you organize your thought and feelings and you can let him know your side without getting derailed with anger.
Please let me know if I can be of further assistance.
If he is being verbally abusive...the letter is the best way to go. Plus, even if he refuses counseling, it can still be an option for you. If one person in a relationship makes changes in atttude, behavior, or communication, the other person will have to make changes. This is called "going in the backdoor."
"I think he knows what I am upset about, but is dismissing it."
It is best in this kind of situation to know for sure before making an assumption about what someone knows or feels. It helps to prevent misunderstandings.
I just checked and she is not online at the moment. You night try to re-list this and put "For Kate" so it will get her attention when she comes back online.
