I'm gonna throw in a scenario I'm surprised I didn't see. The problem with dating a "separated" person is that they have not been single long enough in most cases to be serious if they were not the one that left the marriage. They are trying to "replace" someone with you. When they realize you will never be "the ex" you have become what we call a "REBOUND" and that really sucks for the person who tried to make something out of nothing!!If they were the one that left the marriage they usually want to be "FREE" for awhile and "Taste" whats out there.Either way you usually can't keep them so why bother.Unless of course you just want a cheap fling then your gonna get just that.!!!NO THANKS!!! RUNAWAY!!! I've seen this way too many times.I agree with the moral issue too but everyone gets lonely sometimes and can fall for the poor me type.
