What's going on between you two definitely matters to your wife, a lot. She has further decided that she has nothing to gain by discussions with you. Are you planning divorce? If so, maybe it's best to let your attorney talk to hers. Your wife is aware that you are frustrated by her not wanting to talk about things with you . . . and she's probably enjoying that. So you might move forward with your life and do what you need to do. Don't wait for her input. The silent treatment is her saying she does not need to collaborate with you. It's a way of ignoring you to convey that you've become irrelevant to her. It's meant to be hurtful. She won't change. I'm sorry for the pain this is causing you.
