Allie,
You are likely in an extreme fight/flight fear response. Ironically, what you are afraid of is your H. Your body/emotional self is telling you, correctly, that he is harmful to you. You are hyper-alert, your cortisol will likely be very high, you are on a hair-trigger expecting imminent danger. Others may disagree with this description, but when I was in your shoes,my H's actions felt like emotional violence. No, there is no logic to it. Why does he blame you? Because he is also operating on an extreme fight/flight fear response, but, unlike you, he cannot look at himself, that is unbearable. So he is looking without, through an extremely emotional lens, where he must act to save himself. Alas, all the MLCrs do this. It is not your fault. You do not deserve this. Your H lacks the emotional coping skills to deal with what has now become an existential/identity crisis. I sense from your earlier posts you may have been protecting him emotionally for most of your marriage. Now he has imploded.
This may sound harsh, but I hope it will help you calm yourself from your current state of panic. In many ways, your H has already done the worst of it, he has blown up your marriage. That is not to say that you cannot reconcile in the future, but the marriage as was, it is gone. I had to keep telling myself this, and to not to be afraid of losing what was already lost. It's a very hard pill to swallow, but it does help you deal with the next stages with less fear.
Regarding communication - he doesn't get to say how you communicate. That's your choice. And please note the double standard from him - he can send you things, but you just have to sit there with duct tape on your mouth? I personally think a WTF text is ill advised (albeit cathartic
). I always wrote things out first, and let it sit for a day. Or I read to a friend for a more level head on the matter. It takes some time because at first we at shattered into little pieces, but eventually you will see that you have equal rights in this situation. You are not powerless.
If you can get a break from your current environment, it may be restorative. Go for a walk, visit a friend? Whatever you need to redirect your thoughts for a while. I really get the whole dread of waiting for the next shoe to drop, but often, the anticipation is much, much worse. And often, we can get into a complete stew about nothing.
