Ask archangel Michael to help you cut the cord between you and this person. Visualize Michael drawing up his huge sword and severing the connection.
Good luck. Breaking up is difficult. Sending you love...
I think you said it all when you said: "I think she is a love addict and I was feeling her euphoria and I mistook it for love...This girl isn't someone I really match well with, we have not much in common but that we communicate on this emotional level. I'm more star struck by her, but not sure if it's love. Perhaps crazy love but real love I'm not sure."
You knew she was not a good match for you and yet you were addicted to being with her. It sounds very much as if she got her hooks in to you as a narc. They are good at getting empaths to lower our guards and then they razzle dazzle you on an emotional level. Every story between an empath and narc is almost identical:
The relationship is intense and it's the most deeply you've fallen for someone. And then after a while the use and abuse starts. And after the narc has sucked the life out of you and left you for dead they move on and you are in pieces. Lucky for you you saw the signs and got out when you did. It would have been a mess for you had you stayed (the ex boyfriend etc...).
As for how to move on you do have to cut your cord with her. As an empath you feel so deeply that it will just take some time. I would delete her number from your phone, get rid of pictures and things to keep her out of your mind. Just move on and focus on doing things that make you happy. It sounds like you are pretty aware and smart about who you date. Keep your shield up on future narcs and you'll find the right girl for you.
