I'm pretty sure they can tell if you are smoking. So is there anyway for them to sense what you are smoking. Are there any smell detectors to sniff us out?
aboslutely don't send him anything. nothing hurts worse than not thinking you matter anymore. get your hair cut, get a manicure, get a cute new guy, and randomly run-into him at a place he frequents, and casually introduce him to your new guy as an old-friend. Nothing burns like that. Have fun!
Just move on and dispense with the punishing email. Be glad you discovered the rat when you did. You could have married the loser.
Have you ever heard the saying, There is a thin line between love and hate? Well the hate part means you still have feelings, so the best thing to do is just wash your hands of him and act as if he doesn't exist. Although it may be hard to do, it is a great form of revenge.
call the fire marshall and dont tell the building manager you called. In most cities it is a law that smoke detectors are required. if it is a workplace or a dorm, fire extinguishers are required also.
If you write him it will just make him think of how hung up you are about it. He will just feel like he is a stud because you can't get over him. The best thing to do is take the high road and move on. Sucks because you want revenge but you will find out you are a happier person if can bring yourself to handle things this way. Plus, it will show other people you have class. Other guys will be put off if they think you are the vindictive ex-type.
