I know that she is scared of change but I never had a relationship before so I’m confused as to why it’s sad and not flattering that someone you love is willing to change for the better just for you as their inspiration. Maybe it’s insecurity, feeling like she don’t deserve her or the only reason she loved her is her bad sides, immaturity and dependence on her, she became more independent making her too different from the past her she fell in love with idk this is just sad…
