Ah yes, the “I’m married now so if I let myself go…well then suck it up, buttercup. You’re stuck with me” defense.

If I just up and decided I’m not going to shower very often because we’re in lockdown and I don’t have to get within 2 meters of my employees, I shouldn’t be surprised when my wife loses interest in being within 2 meters of me.

People of all ages don’t necesarily accept undiscussed changes. Sounds to me like you want a one-sided relationship where you can dictate what’s acceptable or not. Maybe you can browbeat your “partner.” That shit don’t work with me.

[edit] added quotes around “partner” as it sounds like you don’t want one, you want a door mat.
