Welcome to MLC land. Sorry that you're here, but you couldn't be in a better bad place.
I'm only 18 months into this, and I haven't read your newcomers thread yet, but I will throw out a couple of quick comments on your post before the experts show up tomorrow (it's all about the time zones LOL).
If your H wants a D, and you do not, do not file regardless of how he pressures you. Make him do the work. Also, I get the feeling that he expects you to use the same L. If he files, please get your own L, not to be confrontational, but to protect your own interests.
If telephone conversations are difficult for you to manage, and you must communicate, can you do it via text or email? I am no longer dealing with any anger or spewage from my H, but I still find written conversations easier to control.
I'll read your original thread tomorrow, and I'm sure others here will as well. You've come to a great place, and you'll find a lot of help and support here.
Hugs.
