Serpentine belt break at 50k - possible underlying issue?

Has anyone else had a serpentine belt break? Mine’s halfway broken. I’m going to get it replaced, but the trusty car person I know said he’s worried it’d break again.

For those of you who have had yours break, was there a reason yours broke? I’m fortunate I wasn’t on the highway when mine broke, but I drive 100 miles round trip multiple days a week and I’m afraid of it happening again if something within the car caused the break.

Thanks in advance!
