Sucks, but they COULD wait 'til after you've already become intimate.

I am sorry dear, and i should of thought before sticking it in!

Doesn't bother me much.

I figure its on them.

That's just wrong!  Why are they dating if they are married in the first place?!  I agree with everyone so far on this topic!  It's immoral, disrespectful, selfish, etc., etc.

If I could give this rating six stars I would.  I don't even think this is a pet peeve I just feel it's simple disrespect PERIOD.  I'm lucky not to have ever experienced this, but this doesn't rule out that I won't.  I've had some female friends that this has happened to and one unfortunately ended up with the bastar*s child due to his dishonesty and infedelity.  I think it shows the person whether man or woman has no respect for their husband/wife or the person they are seeing behind their spouses back and they didn't stop to think for a second about the consequences of hurting the innocent people invovled and if they did it just shows how much their willing to risk for their utter selfish desire.   If however someone finds out or has been told the person they are involved with is married and continues to see them with this knowledge then I have no sympathy for them as that person will never be theirs, EVER, as they were not yours in the first place.  If they cheated on their spouse what makes you special that they wouldn't do the same to you if they decide to leave their spouse?

Actually had this happen to me; but I think kamy is right- this goes a bit beyond "pet peeve".

Well, I haven't come across this one before, but I think it'd fall under the "things that I think are highly immoral" category rather than the "pet peeve" category.
