Most Helpful Girl
Honestly this could just be a phase. I went through my piercing phase and eventually I ended up taking most of them out either I didn't want them anymore or my body rejected them. Now I'm in my tattoo phase lol.
There is a chance that she might just get bored of it eventually. If she doesn't then you should have a talk with her. Tell her how you truly feel about it and see if you two can settle on some sort of compromise.
