I'm going through a problem similar to this, I guess. I moved from NY to Texas, so my girlfriend 0f 3-4 years and I basically broke up. So now she's dating some douche bag in an "indie rock" band, and she has just basically become sort of indifferent, at times cold to me. This really hurts me, because she is my best friend, she's the closest person to me in the world, compounded by the fact that I'm in a new place and alone.
So, I basically just figured it was over, life sucks, and it was time to move on. But she strings me along, she tells me she loves me and that she wants to be with me "down the road," or "in the future," but she can't clearly define when or where that is. So in the meantime, she wants us to be "friends," while she gets to have her cake and eat it to. I on the other hand, am a miserable mess, and I just wait for this "down the road" to arrive. I told her to stop calling me, that I need to break away to get over her, but she just called me more, and for a couple of days anyway was really sweet and loving. Now she's back to indifferent and cold, and I feel like I need to distance myself, get over her, but I can't. She said she'd keep calling me.
