A man returned home and his wife of 10 years greeted him with the revelation that she no longer was attracted to him, didn't love him and wanted a divorce. She already made plans to rent a place nearby. They have 3 children, ages 5 - 8, and she was amenable to joint custody.
He is in denial, and counseling didn't pan out for the couple. My advice was to support her requests, and look at the nearby relocation as a positive- since he would be able to see his kids regularly, and logistics (school, visitation, impromptu plans, etc.) would be quite valuable. He needs to get over the fact that she will most likely not come to her senses and return to him romantically, and inevitably have future lovers. He needs to think first of the best interests of the children, and since they both view each other as good parents, that should remain the focus.
The second attribute is that he should be supportive. Whether he was less than an ideal husband, she is going through an emotional crisis (or mental illness), or otherwise, he best path is to support her decision and not attempt to talk her out of it, as she will eventually come to the same conclusion. He should want her to be happy and stable, which is the right thing for her and their children.
If she reverses her decision, gets necessary counseling or space, she may return to him recognizing his compassion and understanding. In the more probable scenario, she will appreciate that he supported her requests, and it makes the negotiation of community assets easier, and if the former couple can get along, it is much healthier for the children, and will make their lives much easier, as they will be able to rely on each other for child care, and share in critical moments of their children's growth (holidays, birthdays, recitals, graduations, etc).
Marriages are tough, only ~50% survive (post 1990), many that do stay together for reasons other than love and compatibility (e.g., financial duress, children, co-dependence, etc.). If your break up becomes more combative, you really should do everything possible to protect yourself, whether it's your physical or mental well being, self-esteem, financial security, or otherwise.
