There's a lot of twisted logic going on here, lets set this straight, there is a big difference between a drug addled street hooker and a high end escort. Elray is not talking about a hooker. In regards to the morality of it, well if one's wife has committed adultery and you're divorced, you are a free agent.
The idea you should remain pure for years in the hope she's coming back, while she is having sex with multiple someone else's is rediculous, and living in denial of reality.
Which brings me to the next point, Sex is a very important part of a healthy man's life, he needs it to remain sane. Women have no idea in this department what a man deals with and try and shame men into believing they are unreasonable for expecting regular sex in a realtionship. The only women that have any idea what a man goes through are female bodybuilders who have taken male steriods. They've found that even taken at a tenth of the level the average man has in his body, that their sex drive is uncontrollable and had to masterbate several times a day just to function.
In regards to worrying what a MLC'er thinks about what you do with your life after they've left? The MLC'er has no right to any consideration from you and you should not give a damn what they think. Tracking their every movement, kissing their ass and looking for hints of an R is a waste of your life. If you build a new life, with or without someone else, you begin to truly see that you deserve more than they will ever be capable of giving you. You'll probably find as I have that you become too strong to ever fall into the trap again of being the rug they can sweep their toxic crap under again. They have to prove their worthiness, not you.
In terms of the whole standing issue I have some problems with the religious rationalizations some fall back on to remain standing when all other reasons are no longer valid.
Number 1, even biblically if your wife has committed adultery your marriage is over anyway, The vows have been broken, you have grounds for divorce.
Number 2, once divorced they are no longer your wife.
Number 3. If divorced and she's been cohabiting with the OM for a period of time ( depends on state or province) she's technically in a common law marriage. Which means one would be lusting after someone else's wife if still standing at that point.
