I've always felt like if I didn't want to confront another man for my wife's affection, that she may do it for me.
But, no, they will submit to him faster than the husband did.
It does create a helpless feeling.
An ex wife used to go to this one particular bar regularly.
Then it got to a point to where she go alone, and I wasn't invited to accompany her.
Some weeks later, she relented, and we went together.
But, before we went inside, she told me that she has a reputation of being single and available, I better not ruin that rep, and she didn't want me to do anything that would make people think otherwise.
And she took full advantage; talking to other guys that approached her, dancing with them (or others), and play pool with them. If we had a game going, she would ask me to go sit at our table while they played each other.
