From my own experience, my ex stonewalled me until he was ready to talk. There was nothing I could do to open up communication, I tried. I didn't fully grasp how hurtful that behavior is towards one's partner until we were divorced.

OP, I hope she stops stonewalling you. Does she do that to be hurtful? That was my experience. Stonewallers often use control tactics and behave in ways to create emotional pain. I hope it gets better. Tell us what the situation is when you can. We are here to support you. Take care.
