I feel a certain way about this

I am asking because if this were my kid I definitely wouldn't be ok with this.

So my partner has 3 kids. we're together for 8 years. So far my partner hasn't been much included in their kids' friends, so he doesn't have contact with the parents of their kids and he barely has any contact details. It's weird to me but barely my problem.

However this weekend his 13yo went on a sleepover with his friend, at first he didn't even want his dad to drop him off at the correct address. (kid arranged it with his friend) he just asked him to drop him off at a random address his friend used to live at and then they would cycle to his friend's place.. so his dad wasn't even going to have the address his kid would be staying at. I saw all red flags so I did end up mixing in this and told him that wasn't cool, he needs to know where his kid is staying and he needs to have had contact with a supervising adult.. That is like.. bare bare minimum in my opinion.

So that was yesterday. He dropped of his kid, had a conversation with the parents (the parents still don't have my partners contact details and vise versa) and was gone.

Last night 13yo let his dad know that he'd appreciate being picked up by 1:30-2pm.

now 1pm came around and kid asks to stay another night and it's ok for friend's parents.. Dad is ok with this and doesn't double check with parents because he doesn't have contacts.. though doesn't seem to care much?

I feel a certain way about this.. I wouldn't be ok if my ex were so careless with my kids' physical safety.

@Mommaof4

the extra night wouldn't bug me IF dad would have been more acquainted with the kid's parents.. like if parents talk regularly the kids can usually guesstimate that this would come out and trust would be broken. But if parents don't know eachother and have barely had a conversation.. It's easier to take advantage.. and I have a bit more trouble with that.

He didn't lie about it. He told up front to his dad that he should drop him off at the kid's old house and they would ride their bike to the new house..

So with that arrangement dad didn't have the address of the new house and wouldn't have contact with the parents of the kid.

With me mixing in, he did drop off the kid to his friend's house and he did have a conversation with a parent.

I 100% agree
