There is nothing to indicate she is taken, and when she said these comments, nothing indicating her having a boyfriend. When she asked me why I didn't have a girlfriend,there was nothing telling me she has a boyfriend.
There have also been further and even more obvious hints since this time, but because her myspace says shes taken, there is very little I feel I can do. Of course I can drop hints, but this is difficult as I feel I am limited in what I can do because of this taken thing, but I'm worried that she will go silent on me (which has happened before, then shes back to normal), but also tell me that shes taken or not interested. Finding out her status, or that she is not taken, will boost my confidence and help me to tell her how I feel.
Therefore, as I know one of her close mates, I will ask him if she is taken. This is a "strategy" fraught with danger but I have no other option. I would ask her, but I have never had the chance. My only concern is that he will probably tell her what I asked, or he might say he does not know, which would make the question pointless being asked and he would likely tell her, making me look stupid and no better off than before.
