May I ask how you arrived at the conclusion that the husband filed for divorce because of that ugly incident? Sweetheart, did you ask him why he is divorcing his wife, or are you merely adding the dots to form a straight line? In actuality, those same dots you added up to form a straight line could be intended to form a circle.
Honey, don't you think you arrived at a rather hasty conclusion? Did you stop to think that, perhaps, the marriage was already in shambles and the rape was either an unfortunate coincidence or the incident was the last straw that broke the camel's already fragile back? One thing I'm certain of is, no healthy marriage breaks down 2 weeks after a horrendous event. The time frame is suspect and curious.
True, a traumatic occurrence like the sexual violation of a man's wife right under his nose by a group of thieves, may completely cripple a marriage. However, it usually takes a little longer than 2 weeks for such a drastic action. It's usually a steady decline which takes months or years. It starts with a cold war gradually causing an icy distance between the couple, driving them apart slowly but surely until the center can no longer hold.
Another aspect I find curious is that the husband filed for a divorce without first separating for a reasonable time. Being separated for 2 weeks doesn't cut it. They have to live apart for at least 6-12 months, to show that indeed the marriage has broken down irretrievably, before divorce processes are filed and served. What usually happens is, the husband either moves out or asks the wife to move out of the house. Some couples remain separated for years before they finally get a divorce. Some even remain separated and live that way without ever getting divorced, especially older couples whom already have children. What is highly irregular is a husband wanting a divorce from his wife barely 2 weeks after the fact. The courts want the petitioner, the person who filed for the divorce, to have enough time to marinade until such a time as when he/she is absolutely sure that divorce is the best option.
