If by faking it only means going to a meeting once or twice a week now and again I would suggest you consider it but not going from D2D ,I`d draw the line their .
But ultimately this has to be your decision and you are the one that has to live with it whatever the outcome so think seriously about the pros and cons of your decision.
If your parents are agreeable to you faking it maybe they too can help you in this regard making excuses etc for you of inquiring (sticky beaks ) minds.
Living with your aunt could be a good outcome ,however you need to weigh up in the balances what problems that could cause in family relationships .
I hope you find a solution that fits all partys here BlackWolf
Take care.
