If my husband had an inappropriate relationship with a co-worker? I would expect him to leave to job, and go to counseling on his own and with me.
I have known a few people (well, 2) who have gone through this. One couple worked it out, one divorced. The couple that worked, addressed the issues. The husband confronted himself in therapy, as to why he sought attention outside of his vows. They also worked on fixing their marriage. The other couple, not so much. The husband refused to leave the place of employment and cut off contact. He wouldn't go to counseling.
