My husband wants to divorce me for reasons that don’t exist. How can I cope ?

I want to start out that I love my husband, we’ve been together for 14 years

He also has significant mental health challenges.

He recently lost his job, to cope, went on Paxil, had a manic event, is accusing me of cheating (because of circumstances that aren’t just coincidence- like I’m buying new clothes quite a bit, but I’ve also lost 40 pounds since this time last year) but I haven’t cheated.

I’m bereft, I’m out of my mind grieving

What do I do? How do I get through the next few days? I really hope that once his head clears up, he’ll want to come home.

Despite all of this I’m not mad. Would I be mad if he had pneumonia?

Just help me get through the hours.
