A guy I know introduces a female to us as the woman who was in love with his brother.
This young lady says that he always do that talk about her and his brother. Apparently a very long time ago these two were an item first but he was living with another female at the then so he was cheating.At one time I guess because of that situation they had to take a break.

The young man brother who is like 4 yrs younger took that opportunity to hit on the chic he was having sex with. This guy the one I know had no idea at the time but found out.
There was nothing he could do because he was in a relationship.The brother told this lady
the brother was mad at him because of it and she had no idea.Long story shorten long time ago. Now that yrs went on those two rekindled and whenever he sees someone and introduces her he refers to her as the one his brother was in love with he brings it up.

I am on here because yes I know him and I am asking because it is a message board. He ask us men and woman on job is it wrong of him doing that.

I think it's callous cheap and disgusting to air ones personal business to strangers, and no doubt this fellow who does this to this female is as I have described, but also the female is not very repectful of herself, or her privacy, to allow such behavior, or even be with the boob!

Hard to respect either of them frankly!

Yes it is . I can't say I am not in her shoes but I guess the question was why would he even do it . That was in the past

Because he is an idiot? What else would you need to know? Does that make her one too? Somewhat, so he is but part of the problem.

He does it because he is immature and spiteful, and she should have not been "keeping it in the family" Why is she with him?

She originally was with him first.i don't know why she back

I think in general it is none of anyone's business of how he introduces someone. And if as it appears so many people, know of who is having sex with who, I guess it does not really matter

Evidently it is because someone in that situation have a problem with it

One of my brothers politely and properly knocked the teeth out of non-gentleman that had decided he was going to trash a woman's reputation by publicly disclosing his sexually conquest of the woman....My brother asked him to stop, he didn't, and the guy ended up losing his teeth.....I don't advocate violence BUT, sometimes, a man can not be expected ignore filthy, evil behavior and not stomp-out the stupidity of a dumb bastard when he won't stop being a dumb bastard.
