<human>: Can you provide a brief rundown of the text in within 3 sentences?

I was just hoping for a few sounding boards here, because I think I know what I have to do but I don't know how.  So, I've known this girl for about 11 years, we dated once when we were younger, and got back together three years ago.  We went on break, or so it was called, a couple of months ago, and it's been terrible.  Some days it's like we never stopped dating, others I get called things like human scum, told that I can never help her, and that she'll never trust me (for reasons she didn't say).  As things stand, there's no way to go from break back to dating, and I'm slated to spend a lot of time with her in the next few months in limbo.  Despite all that, I'm still extremely attached to her, and don't know how to let it go without it becoming a blowout fight and losing the friendship.  Does anyone have any advice?
<bot>: Been on a break that has no hope of going back to a relationship, but I feel stuck because of attachment.  How do I take the next step?
