Wait a minute here - his complaint was that she didn't initiate sex. He's upset with her for not meeting his unspoken metrics and for failing his sneaky test. Women tend to have more responsive sexuality, rather than the spontaneous sort that men are more likely to have. If she's exhausted, sick, bored, and kind of fed up with his passive aggressive tantrums, which she notes are common, she's not going to even consider initiating sex because it's just not on her radar under those circumstances. He should have talked to her as a partner about this issue, instead of throwing a hissy fit that makes a bunch of assumptions.
