Don't read anything into the lease. He's not thinking clearly. Even if he does that and then wants to reconcile, you'll both find a way through it.
The only other advice I can offer is take care of you. This time is so very hard and you're doing so well with it. Get a massage, do something decadent, go out and listen to live music. Get out and live to the best you can. That's all you can do and it will definitely help.
