All I can do is shake my head. Your h is over the top. He doesn't realize that you could expose him for being a nut job about food and him living in that stinky dorm room for many months...now, to me, that makes him look like the unstable one. But, you will play fair until the very end. BTW, your h reminds me so much of how my xh behaved during the process.
He really is attempting to gas light you in many ways and to state you had to see a therapist is a very low blow, imo. Please, please do not allow him to get into your head. You now have a very clear view of who you are dealing with and he is going to be one of those that will continue to fight you and the judicial system no matter how he looks. He's not going to listen to a thing that they tell him because he's bucking the "authority" in his mind.
I am so sorry about the fender bender, but at least you had a friend come to your rescue and that will burn your h's chops because he doesn't have control over that either. I bet he was "hot" over the fact that you found a way around his game of "mine" and not "sharing". His little game w/the cars will be over soon enough as the one is in both names and since he has two...he may have to count that as a marital asset that will need to be discussed. Good luck w/the car shopping and I am glad you are okay.
Continue to document because the stuff he's sending you shows just how unstable he is. Be careful and walk around your car and check around you house periodically. I do not put anything past this guy.
