Depends on intensity of thoughts. This OP said things like he hated to be around his wife, found her boring, was not interested in anything she was interested in, was not attracted to her as a person. He also said he felt his marriage was like a business partnership. Would you want to be with someone looking across the dinner table at you with these kinds of thoughts running through their head? I know people who put up with not just thoughts but a stream of daily verbal abuse from their partner. Yet they stay. To each his own. I just gave my opinion...
