Well, it certainly depends. I can relate to that. When I used to gig once or twice almost every week, I changed my strings every week. Sometimes I still broke a string on the 2nd gig of the week. Used to buy 10 sets at once when I did.

But, back then I was using an .11 to .52 or .54 sets and Jazz III picks...I played rhythm only, Les Paul with a booster to Fender DeVille, and rather heavily I guess. This was after 2 years of playing the bass (with a pick).

In recent years I not only play much less but also down to even as low as .9 to 40 sets, and I never break a string no more. Completely different style of playing, too. I have, um, six or seven guitars I play now and then, and I tend to change the strings on them roughly yearly, or before a gig.
Sometimes, however, actually quite often, I just put in a set and play it maybe twice before I throw it out in favor of something entirely different...but that's not due to string wear, just the desire to try another kind of a set. And of course that also includes adjusting the neck and intonation every time.
