I like her husband approach, he's not making big fuss over it but he's obviously hurt and wants a divorce which I totally understand, if she cheated on him they should just end their relationship
no need for scenes just let's decide to split up
his mother on the other hand...
also i just want to add that what ayano feels is not love, plain and simple, its infatuation and once hormones cool down in a year or so she might end up with a person she knows absolutely nothing about and they might be not compatible at all and she as a 30 something yo should know better
but unlike other comments i dont really hate her because i respect her honesty, much better she told her husband than just continued cheating behind his back
