A report on "coping with separation" (relationship breakdown)

The report should be written when one partner (the female) wants to end the relationship with her male partner/husband after she has had an affair. The report should be styled with how the rejected partner should cope with separation having been in a relationship with the partner for over 20 years. The report should contain at least 10 headings or chapters on how to deal or cope with separation. What he/she should do or not do. If you like it should be written in the style so that the reader gets value and advice on what to do themselves if they find they are in the same or similar situation. Each heading or chapter should be titled to set the scenario and the content under each heading should detail what the rejected partner should do to help them through the pain and distress they are feeling following the discovery of their partner having an affair and wanting separation. I hope I have made myself clear on my requirements? If not then please tell me! Thank you, Craig
