If it works for them (him) then so be it. Though notice how she mentions how she’s become a better wife and it’s made him happy, but there’s no mention of change on his part. This is going to be harsh but whatever: Their marriage isn’t working out and there’s some outside force that keeps her there, whether it be religious or social pressure or financial reasons. So she’s found a way to cope and make huge changes for her husband, and of course he’s happy because he’s getting the benefits. Meanwhile she’s playing dress-up and pretending every day that she’s not pushing 50 and not with someone whom she’s not happy with. If she can keep this up, she needs to go to the next open auditions near her.
