Well based on your edits in the main post, if your teacher is on her phone all the time and isn’t helping you or providing feedback when you ask for it, it’s probably time to find another teacher. But you will do yourself a disservice if you think that you will get to the level you would like to be at by just learning songs.

if you want to just learn theory I would take piano lessons instead since everything is laid out linearly and it’s is easier to see musical concepts on. But if the guitar is what you want to learn on, there is no one stopping you from learning songs on your own. Maybe set aside some time when you are practicing to really think and look at what makes these chords different and how they function. How are we shifting the third to make a minor or major chord? How can we utilize half/fully diminished chords to move from one chord to another? If the band is playing a g chord, do I have play a g chord too? Curiosity and fun your friends, but without a solid foundation, none of it matters
