Depends what “fix” means, but if you didn’t get ripped off for $200, yes.

Getting it professionally tuned isn’t unreasonable imo, especially if the neck/pegs are misaligned, but in no world should that cost $200 (and don’t try to fix a misalignment).

Once you start making changes that can’t be undone, you’ve crossed the line. Get it tuned, get a nice strap (with mounting hardware, if needed), get a polishing kit or nicer case, hell, even get a replacement bridge/pegs and tools for working with a guitar, but don’t make permanent changes yourself (or have anyone else do so). All of those together could be well over $200, but you’d describe that as a tuneup and buying accessories, not taking the guitar “to a pro to fix it.”

Caveat that some people don’t like non-musicians or anyone else even touching their instruments, but I’d like to think that would be obvious to a spouse, even one who might have assumed that permanent changes to an instrument they don’t own are okay.

I’m a non-musician and my husband has a somewhat beaten up, but favored instrument that he learned on, so I’ll send this to him to see if my instinct is right (for my relationship, which does not mean it would be right for anyone else).

Though tbf, even thinking it might be okay, I got my husband a new instrument instead of messing with his beloved one, just because it occurred to me that he might react like the husband in the OP, and I didn’t want to risk it. Of course, he could also have then felt guilty about using the new one because it’s not the one he loves and felt guilty about using the old one because I gifted him a “nicer” one. I was lucky in that he’d already branched out into related instruments and the new one could fill a new niche, so wouldn’t compete with the old, making me less worried about him feeling conflicted [I'm so sorry about that sentence, I’m imagining trying to structure it in German without nominalizing any of the clauses and… woof].
