I'd hope that nobody would disagree with this.

The toxic aspect isn't from wanting space apart from your spouse, it's in sending signals (even ironically or in jest) that the family you are a part of is something you hate, that your family is cramping your individuality, and that you want to escape from them.

Everyone needs their own time and space. Just because you married another human doesn't make you any less of an individual, and having healthy opportunity for time apart is essential.
