we don't know if the problem is his, her, or a combination of both of theirs. we know in shrizl's eyes, it's his problem, he has no reason to be insecure, etc she's never cheated. but that doesn't mean that in the context of their relationship, interactions and dynamic, he doesn't have a reason to feel insecure. how do we know? shrizl might not even realize it. that's all I'm saying. and just because she has never actually cheated, doesn't mean she doesn't hang out with these guys because she likes and enjoys the attention she gets. maybe that's why the husband is uncomfortable.
