During my wife's affair during the summer of '07, she was driving a two year old BMW 530, and I was driving a 2002 Acura with 140,000 miles on it. Once her affair was out in the open, and our relationship was at its worst, I took to driving the BMW (whose 700/mo. lease payment I paid for) occasionally, "just because." She didn't let on that it bothered her, but I know it did.
The best story I have was the day that I followed her and watched while she met up with her boyfriend in a department store parking lot. It was raining, and they sat in her car for almost an hour (damned tinted windows!), and then got out, locked it up, and got into HIS beat up old truck, and drove off to his house (his parents' house, actually, as he lived with his mom and dad).
I was FREAKING OUT, complete with an anxiety attack (one of three I got during her affair), and needed to be talked down off the ledge, so to speak. Using a bit of humor, I think, to calm me down, the poster from the SSM board who ws helping me, NOP, asked me if I had a spare key to her BMW. I think this was his wife's idea, actually. "Yeah, I think so," I said, "but it's at home."
"How far away is your house from where you are?" he asked."
"Oh, only about five minutes," I said.
"Go home and get the spare key," he advised. "Then drive to the parking lot where her car is, park yours near there, leaving your key for her under your mat and the door unlocked. Then take HER car and drive off. When the love birds get back from their midday rendezvous, all aglow, she'll see your car, hers gone, and know she's BUSTED and you'll totally ruin it for them."
Sometimes, you just gotta see the game in it, or else you'll go crazy. Puppy
