This is a subject that seasoned Personal Trainers can shed tons of light upon.
Stay away from them. It NEVER ends well, I don't care how many times she say's *no strings attached* ~ the reality of that statement is based on only her big unconscious mouth and pussy.
They (usually) have an agenda. Many times it is so that she can go home and use YOU to get back at her husband.
More often than not, they will show up. They may not be looking for a fight, but they will distract you because you just don't know what a crazy husband is capable of (and neither does she)
Not it worth it, especially if they show up at your work. Very unprofessional, and EVERYONE see's it and knows exactly what is going on.
There are enough single women out their (with baggage) so why choose a married woman with EXCESS baggage, husbands and children? It's not too tough to ruin your business with this type of behavior. Overlooking her come-on's can do wonders for your longevity.
Now, if you ever get married, wouldn't you expect some type of Kharma to help you "come full circle?"
NOT WORTH IT (speaking from experience, not just out my ass)
