My husband has been struggling and won't come home

My husband has been having a hard time with his depression even though he won't tell me. He decided to stay at his dad's for a couple days. I spoke to his father on the phone to make a game plan. We at the moment don't have insurance and if he needs to go impatient we may have to pay out of pocket. I'm stressed out about that, but at the same time I know keeping my husband alive is more important. He claims he's fine but do you get the "He's fine" vibes from these texts? Even his dad is picking up that something is wrong. We're gonna need to figure out a game plan and that's kinda hard when you don't have insurance.
