I wish TEO would pop on and answer some of the good posts on the board to this problem.
This is a toughie. So much involved. The why she doesn't want to go? How bad do you want to still travel? Is there a 'if you go' anger lingering behind her statement or is it really ok to leave the family? Is it cool really in a way to leave the family and go on your own without guilt and WAY MORE.
best of luck working thru it all. a fast post won't help you, time to evalute your life and situation and take the right path.
