Gasp... Think of the children!
Gasp... Think of the children, the ones you two would have had and the arguments over how to raise them. Then, count to three and run as far away as you can from her and any remnant of the fantasy you may be holding on to. When you are feeling lonely and mistakenly thinking fondly about what might have been, try this five step sure-fire exercise for ridding yourself of the any urge to contact her:
1. Stand up.
2. Make some room around you with some aikido-like hand movements.
3. Along with making frequent, sharp, bokken-tsuki thrusts with your index finger out at towards your absent, imaginary future ex-wife, say the following line (with gusto) using your best Jack Nicholson voice,
You can't handle the truth!"
4. Smirk widely for a second.
5. Resume whatever regularly scheduled programming you tend to run in your head.
...spare me any grief...
