Hey Pommy,

Just chiming in to second what Wayfarer said. I deal with smaller versions of the gym equipment thing with H all the time. He hasn’t lived here in almost 2 YEARS and he still does weird things like help himself to food, go through the hall closer to find things, getting in the bath tub with our daughter. It’s BIZARRE and confusing and actually really annoying. I totally get the strong the urge to want to shout “you can’t do that! You don’t live here! You chose to leave!” but every time I’ve reacted that way I’ve regretted it after.
Wayfarer is right, the more calmly and casually you can handle it (because I’m not suggesting you shouldn’t bring it up) the more he has to examine what he’s doing and why, rather than focusing on your reaction to it.

Last night H went into my kitchen and helped himself to cookies D4 and I had baked. My ego was like “F***K THAT YOU CANT HAVE IT BOTH WAYS” but I just gave him a slightly odd look “ like huh, that’s weird for you to do” and didn’t say a word.
