Tell her you really want to make it work and you're willing to work towards improving things with the two of you but if she wont tell you what's wrong; there's nothing you can do. Agree to a separation and put the ball in her court. Of course cross your fingers while you wait. What do the other Oracle members think?
BTW, I have a GF.
"Oh Lord it's hard to be humble, when you're perfect in every way. I can't wait to look in the mirror, cause I get better loking each day. To know me is to love me, I must be a hell of a man. Oh Lord it's hard to be humble, but I'm doing the best that I can." Mac Davis
