I think you're absolutely right, she didn't think that you were going to change. Sometimes it is helpful to put yourself in her situation. If you had someone who was constantly questioning your feelings or always arguing with you, it would probably push you away a little. The best thing to do is not blame yourself, but make yourself better. It is amazing that you are seeing a therapist to try to fix yourself! You are taking the right steps towards making a better you Fact is if you are not confident and secure with yourself, there is no way your relationship could be successful. In this case, I would not continue a friendship with her. It seems as though your feelings are so strong that it might hurt you even more to just be friends. In my opinion, I think it is best to explain to her your situation, i.e. "I love you, but I need to work on myself right now. I appreciate your friendship but I feel as though that will only slow my recovery process. I am always here for you and if you need anything, please let me know". It shows that you care for her so much that you are willing to let her go to become a better you. This may not be the response you were hoping for and I know I don't know your relationship personally, but sometimes it's better just to let people go. The person you are supposed to be with is out there somewhere and you just have to remember that there will be another girl that loves you as much as you love her. I hope this helped you! Good luck with everything!
