I had a girl friend very much like that. Would always get shitty even if i spoke about a mate to some one...
Best thing i ever did was walk away
Sure, she had great looks, a great figure (she reckoned she was a bell bottomed pear), and a mum with a big purse.
What else could she control you in doing ?
Ban you from the 'club ?
Put your foot down, stand your ground.
And if she really wants you she'll learn to live with your friends without back stabbing or trying to play them off
And on a lighter note
I wouldn't have clue with the aeroguard
