Hello Noodle4002,
Thanks for that info and choosing the Apple Support Communities. If I understand correctly, you are deleting songs from the Music app on your iPhone, and these songs are also being deleted from your iTunes library on your Mac. This could be because you have iCloud Music Library enabled, which syncs your songs between your devices. Please check the info and steps in this Apple resource on this situation.
Cheers!
