She's leading you on IOT cause strife between the two of you, the mere thought of which gets her wet. Forewarn your mate, go round to hers, and administer a stupefying drug with intent. After she's chundered in the coal-scuttle and passed out in the aspidistras, let your mate in.
Then both of you can have your snuffling, stoatish way with her.
If she sent a photo then it is your duty to post it on here. Failing to do so is another indicator of gayness.
Sounds to me like you need to steer well clear of her. Bitter, psycho, bunny-boiling mate's-ex's are not the best recipe for an untroubled social life. Get down the NAAFI and shag some mentally retarded but psychologically uncomplicated fat slapper if you want to get rid of some dirty water.
I'm assuming its not a lasting and fulfilling relationship that you are after?
Remember MontgomeryofAlamein01 a couple of years back? Failed to post pictures under similar circumstances? A week later he put his Mondeo under a 16 wheel gravel truck? I couldnt make it to the funeral but I'm told his Mum laid on a lovely ham tea.
Do it and as stated pics must be posted. Your mate will forgive you just tell him how sorry you are and buy him a load of beer and he will say "well fuck her" and you will say "I did" and you will both laugh with a stronger friendship.
