My ex and I have a very weird co-parenting relationship, so I might be biased, but I see nothing wrong with letting a CHILD use the bathroom. Then again my daughter's were in my ex's wedding (not his daughters) and I even have the ex-wife after me (ex is on 3rd relationship) over for visits to see the (ex) stepson. We went to her new wedding as well

Sounds like the new wife is jealous of the ex and her sister is just stirring the pot and putting stupid ideas in her sisters head. He needs to put her in her place or he just might be divorced again

I may have missed it, but did OP mention to his wife and their guests that his ex and her children were stopping in briefly to allow one of the children to use the restroom? That would be my only soft scolding I'd give him - let your wife and guests know that it was happening. Otherwise NTA for letting a kid go to the bathroom rather than forcing them to hold it.

A child needed the bathroom. Who would say no? You just say yes! It's his kids half brother for crying out loud!!!

NTA, but your new wife and her sister are definitely a******s.

Sounds like the new wife lacks self confidence and has a jealousy problem that she tries to deal with by being controlling. I have 3 kids with my first husband and my second husband and I have actually let my ex stay with us a few days when he was in great financial straights. My husband was not jealous because he knew we were divorced for a reason, and that I did not want my ex back. We let him stay because he is the father of my children and I did not want to stress my kids by them worrying about their dad sleeping in his car and not having food to eat.

Whatever happened to common decency - OPs wife certainly doesn't have any.

"You won't understand." Try me. Seriously. I can think of a number of reasons why this would be considered inappropriate. None of those reasons are *good* or *justifiable* reasons. So am I to understand these women are petty a**holes? Because that's what they're telling us here. A child, the sibling of your step son, had to pee. The mother asked, got permission from an adult in the household. She apologized for the inconvenience. She had a brief chat with known friends. And politely exited without causing drama or overstaying her welcome. Where's the problem?

Wow or even imagine this.... Letting the ex herself use the bathroom! Would have blown current screw loose wife's mind. The part about refusing to communicate and explain her feelings makes it just that much worse. She's pissed that the friends don't hate her and is likely so insecure that she's wondering if they like her more.

I hate my ex wife but I wouldn't punish her kids.

Common human decency. You let a small child go potty. Omg your wife needs to grow tf up. Her and her sister. Seriously?!?!

W in T actual F did the wife expect him to do? Say "Sorry, your child should wet themselves because my wife is too insecure to let them use our bathroom"? That's seriously messed up. He and his wife need to have a long talk about why she's feeling this way, because if she wasn't threatened basic decency would mean her saying yes without reservations.

Of course he was right. Any normal person would have done the same.

Definitely NTA - you did nothing wrong. You & your ex-wife acted like decent, civilized human beings. She asked your permission before coming up - she did not barge in, make a drink, sit down, & take over the party. Your & her co-parenting style is admirable & is wonderful for all the kids. Even if your wife says you wouldn't understand why she was so upset, in fairness she should tell you - maybe you won't understand it or won't agree (& FGS don't tell her she "shouldn't feel that way" - her feelings are her feelings) but you have the right to know why she's accusing you of egregious behavior. Interesting that she said you should have asked her "permission." It's your home too - you shouldn't be expected to ask. If you had & she refused to let your son's sibling use the bathroom in your home, I wonder what her alternative suggestion would have been for the poor little kid - wouldn't care where he peed - just not in her house? For the sake of the children I hope she's on the same page as you & your ex-wife in the co-parenting, that there's not some animosity you're not aware of but that the children might sense. Her sister: It's not surprising that she sided with your wife but it's not her place to insert herself into a matter that concerns only the 2 of you. Sounds like there was a little "piling on" by the sister & fanning the flames.

Next time she needs a glass of water and her child (unrelated to both home-holders) wants to play with that toy they saw last time. Next time Can you watch this random child while I pick up prescriptions Only half an hour. Next Imto your sofa Im Bushed, do you have a soda/beer? Let the kids play. You can go out later and sorry I caught you refinishing your kitchen I won't tell anyone you live like this.

Just told by Spencer's former slave to Let It Go. That is the definition of minimizing. This is a SOCIAL MEDIA site. I happen to be a socioplitiocian and I am aware of this phonomenon and I do not "let go" certain things Nowhere ever was the child actually needing to pee. It could have been poop, a lie, a child who was badly soiled/contagious. But it doesn't matter. Does it. No one in any culture I am aware of uses essentially a stranger's home toilet. And that is a human right. The child did not need water or electrolytes or heat relief. YOU let it go. I never served a person in real need who has these entitled concepts. Why don't the dispossed just come using random toilets on demand. Since this woman has At Least 2 children now she should be on top of it except that her "freind group" was with her ex and she wasn't invited. Stop with the BS and the songs.
