I haven't thrown any child out and don't expect to ever have to, but then the idea that any of my children would be in their 20's, as some actually are, and think that treating me as a skivvy, being rude and bad tempered, leaving me 2 weeks of laundry for them AND a boyfriend would actually fly in this house, is unthinkable.
I most definitely wouldn't be allowing MY home to be used by selfish partners that think they can treat me poorly in MY home.
Lots of women on MN accept very poor treatment from men in general, and I suppose for some it might extend to their childrens boyfriends, who knows.
They also allow themselves to be treated very poorly for an extended period of time until they are finally, understandably, at breaking point.
Unfortunately as is often the case, people who have boundaries often get accused of being controlling or worse🙄.
Funny how people without boundaries absolutely hate them in others.
Far better IMO to be clear and calm about your boundaries in your home and what is acceptable.
Parents that do this don't have this drama because it is far less likely to happen, and if it reared its head it would be quickly checked.
It is possible to have a calm welcoming house where your childrens friends are welcome, without it ending up that you have the type of imposition that has been described here.
Early intervention being key.
But that takes boundaries.
