This! She thinks women mature faster than men and its natural for men to look/want to sleep with lots of women so it's all the women's fault.She’s deluded herself into thinking that the “women” lead him astray.
It's hard for me to understand because I'm completely the opposite. Women don't owe me anything, my husband does. Sure it'd be great if women didn't persue/see married/similar men but they have their reasons for doing so and only my husband needs to be faithful to me. If a naked women knocked on the door now asking for my husband so she can declare her undying love I'd be like 'honey, it's for you', either he can tell her no thanks or leave with her but if I try and prevent her talking to him, she will just do it when I not around and I'd rather know if he's loyal or not! Also, if he goes, what has she really 'won'? A cheat who will bounce as soon as another woman shows interest! However, I assume Jac convinces herself it's it's womens fault as a self-preservation thing, it's easier to put the fault on a woman you aren't married to than a man you are married to, live with and have children with. It's really sad but until/unless she is ready she will never see his faults and leave him and as they have kids it's possibly more difficult than if they didn't.
