Yes, a 100%. You are just hurting yourself, and I've been saying it many times. You are inventing yourself hope, I know it is hard to let go, we've all been there. We are using our heads and past experience to tell you what is best. She needs space and you need space also, stop giving yourself hope and move on already!
Sorry to sound harsh but I hope this is a wake up call and it's that you don't hurt yourself even more.
