<human>: My BF began seeing a therapist and taking Prozac at the beginning of March when he finally got the courage to seek treatment for longtime anxiety issues. Our relationship--we're nearing 3 years together-- always presented us with challenges. But his period of receiving treatment (basically the entire months of March and April) were the best we've had because we were each communicating more openly and having constructive conversations about where we see ourselves in the future. 

Enter the beginning of May: my BF finds out the therapist he's seeing is not within his insurance network. He gets hit with a big bill and stops going to therapy. He's not taking Prozac anymore because he no longer has a doctor to authorize a refill. He lives in a pretty small town and says none of the providers near him have any availability. Finding another therapist isn't a priority for him, and he keeps telling me he feels fine.

Now, I know stigma, shame, and feeling he could manage the issue himself are the big reasons why it took him so long to get help for his anxiety. In fact, the impetus for him starting treatment was me breaking up with him at the end of February. In general, he's not the type to take action on things in his life until he's already at the edge of a cliff.  

Since he's stopped getting treatment, the same old issues are beginning to plague us again: his grumpiness putting us in a cycle of ongoing minor arguments, him not communicating effectively, him expressing constant worry about work and questioning whether I really like him, etc. 

It's been made clear to me in the past that he doesn't want to discuss what's underlying his anxiety issues with me--and I respect that. That's a big part of what a therapist is for. Now he's not communicating with a professional, and it's starting to hurt our relationship again. How do I express my concern for his health and our relationship while respecting the financial and practical issues he's facing around securing an in-network therapist?

Could you distill the essence of the text into 1-3 sentences?
<bot>: BF prematurely stopped receiving treatment for anxiety disorder out of the blue, and I'm unsure how to voice to him that I feel he needs to get back to seeing a therapist and taking an anxiety med.
