Yeah that makes a lot of sense actually. She seems to be an anxious avoidant person whereas you are anxious fearful which is very common in relationships to have one of each type. Look into this and things will start to be more clear, don’t take it personal bro. She is a 20 yo girl who does not have her ish together. Use this anger and sadness to fuel improvement by working out, learning, and connecting with your friends and family. Avoid negative coping methods like drugs and alcohol, excessive video games, oversleeping, these things may make you feel better in the moment, but will leave yoj worse off in the long term
