Nav, George - I don't think that biteme is insinuating incest AT ALL. These two children ARE NOT brother and sister - their parents are lovers. Their is no legal commitment of any sort here.
I agree with Warik.
*heavens open and I side step lightning*
I am one of the most liberal people around when it comes to human sexuality. I was born and raised in the US but my upbringing was very European (they tend to be far less uptight then Americans when it comes to matters of nudity/sexuality/sleeping arangements/bodily functions, etc) and I WOULD BE UPSET BY THIS.
I think that it was VERY IRRESPONSIBLE and disrespectful of the children for the two adults to share a bed...
If the children didn't mind sleeping in the same bed, I wouldn't be thrilled about it, but I wouldn't have a cow either. My girls have shared a bed with each other and their cousins (male and female) since they were out of the crib (barely 2).
BUT - I would not share a bed with a lover in front of my children or even under the same roof. We could be fully clothed, it wouldn't matter. I am open with my children and THEY KNOW that when a man and a woman share a bed it is because their relationship IS PHYSICAL. Perhaps if they were older (meaning teens) I might view this differently, but for now, it is my opinion.
Biteme - I think your ex and her boyfriend are disrespectful and irresponsible, but she won't be losing custody over something like this. To even pursue it legally is an excerise in futility and an expensive one at that. The best you can do is TRY to talk to your ex and her boyfriend LIKE ADULTS WITHOUT THE CHILDREN PRESENT. If that doesn't work, talk to your daughter and ask her how she feels about it. If it doesn't bother her, then it shouldn't bother you. BUT, if she is bothered tell her to stand up for herself and tell her mother how she feels. If she feels "uncomfortable" with this option then tell her that she can always call you or talk to you.
I know it's hard, believe me.... my husband won't be poking any puddy any time soon as he is far too obsessed with my comings and goings, but eventually *GOD I HOPE* he'll be getting a life of his own. I don't know what kind of situations will arise. I can only continue to talk to my girls about EVERYTHING and try to make them feel like they can come to me with anything.
