Well especially with more info it seems like OP gets the sahm struggles and is doing what he can to give her alone time, but she’s saying it’s not enough while also not reciprocating at all. The whole one persons need is another want and hard to determine a baseline of which is more important without knowing what we’re talking about.

I just wasn’t sure whether her needs were just 30 minutes alone to talk to a friend vs his need to be in the garage for half a day - which in that case the needs aren’t equal. But it seems like it’s the reverse - she’s getting a higher level of needs accommodated than him. Asking for a 5th candy bar stating she needs it when he’s just asking for one candy bar.
