Sorry to hear you are going through this, especially when it sounds like you don't have much support where you are right now.
Your situation sounds similar to my initial BD and has a lot of the same elements. I won't rehash the whole thing, but basically we were not being intimate and rather would just hang out in front of the tv each night. We were best friends but she said it had felt like we'd become brother and sister. She suggested a separation to find what each other wanted.
Through dumb luck, I DB'd without really knowing it. I went out and had a life and asked very little of what she was up to, I acted as if we were separating and I was upbeat and positive. After 4-5 months of this I felt a change and she even asked me if I wanted to end the separation. Unfortunately I was not on this forum or wise in the ways of DB and I blew the chance by just thinking all was ok again and going back to normal. What followed has not been pleasant or pretty.
Follow the DB rules, listen to the advice on here because it sounds like you are in a great place to turn this around if you want to. Learn as much as you can about relationships, attraction and yourself.
You can do this, we're all here for you.
