I'm new to this stepparent world, I have certain boundaries in mind while my partner almost has none.
My partner has 3 children by 3 different mothers & his children have other siblings by their mothers (we have none together but I have a 5 yo and a 14 yo by my ex-husband).
I moved into his home almost 2 years ago and his children came over on a set schedule. As time has gone on, I've realized that in order for him to "keep the peace" as he says it, he pretty much allows his children's mothers to do as they please with dropping the kids off whenever so they can go on vacation, get their hair done, hang out, etc. and now they're even dropping off the other kids so their siblings can watch them at our house. His kids are 15, 14 & 5. Their siblings are 8 & 3. I don't feel comfortable having a house full of kids with no adult supervision and when I say that, he makes it seem like I have an issue with the kids when in reality I have an issue with the mothers.
I also find out from his kids, not him, that their siblings are coming over or staying the night. Only when I bring it to him does he say anything.
Is it me? Is it him? Is there another way I can bring this topic up without him feeling offended?
