you aren't his mother, you don't have to clean up after a fully grown adult man-child. he needs to get off his ass and clean up after himself and help with the girls.
I won’t lie my husband’s a bit of a man child at cleaning up after himself, especially his share of the bedroom, literally lives like a teenager. (Clothes, water bottles bottles, wrappers) I used to get really mad but now I’ve just changed our room around so I can’t see his side of the bed floor and I don’t touch it. Hopefully it will get through that I ain’t his mother
When my partner was doing this I started literally gathering all his shit and dumping it in a pile in the middle of the room, when he asked me why I replied "obviously your vision is failing you so I thought I'd help you out". I do this when he leaves his toiletries all over the bathroom too, dump them on his drawers or his side of the bed. He's gotten much better at picking up after himself, if he hadn't I would have just started putting the shit he left everywhere in black bags since clearly he doesn't care about his belongings they can be tossed right?
Update: I had a VERY long talk with him and told him to look at our girls and tell them he wants them to grow up in filth and if he can’t manage to pick up he can leave so far my house Is clean
That’s a hard pill because that sounds like it’s gonna be a repetitive cycle and that he isn’t willing to even compromise and that can be where the issue comes in at! Because most boys moms clean up after that but at least be willing to learn
