She's playing you ..it's a game ..sounds like you are better off without her ...it's not healthy

I was attached to someone online once in hopes they would change and they went and attached themselves to the first empty headed mess that would give them the time of day.

Wait, so she's saying she's attached to you one minute but "emotionally unavailable" the second? That makes no fucking sense.

My gut is that she's a game player. No es bueno.
