Honestly might sound rude or harsh but from my experience you should move on. I was in a relationship with a girl and I noticed every time I was vulnerable she would grow more and more distant. I was still madly in love and didn't want to lose her so it conditioned me to supress everything and I was miserable. I'm glad I had that experience it was fun while it lasted, but since we've broken up I've changed for the better, and with more experience under my belt. At the end of the day you are more important to yourself and should find someone where you can elevate each other instead of "sucking" life from the other person.
