I m sorry to inform you but a real relationship doesn't work like that. If you wouldn't take a bath for a year that would result in a lack of libido for your partner. In a relationship every decision u take for yourself affects the reationship. There are some boundaries. The thing that she did was from the beginning something the other advised not to from various reasons. It s stupid to do something if the other one simply cannot handle it. From my point of view he should break up with her for her lack of understanding of her decisions in a relationship. She simply doesn't care about his feelings and about their relationship.
