I have the answer. We learn from life. This is a 6 step plan but you will learn from this plan if you do this my way.
Step 1
Marry the woman after she divorces her husband. Doing it in California is best for this to really work. You got this so far? Okay great.
Step 2
Make sure the marriage lasts more than 1 year.
Step 3
Suffer when she starts fucking some other loser while still married to you. Sit around wondering what you did to deserve to be crushed in such a total fashion by the woman you love (remember all that gooooood road head you used to get while she was married to that other guy?).
Step 4
Give her HALF of what you have in the divorce as she drives her next future husband around in the car you helped pay for.
Step 5
Learn from the school of hard knocks what you obviously do not now know. Screwing with the lives of others in such a casual and selfish way as you are now is one of the most fucked up things one human being can do to another. After you have suffered enough ... as you have helped her husband suffer ... you may evolve enough to come to the understanding that morals and ethics aren't a theory but a real way of deciding how we should treat the people around us.
Step 6
Stop fucking married women.
