Yes. This is when most people go for divorces, leave their kids to find ‘excitement’ in someone new (who is willing and stupid enough). While a lot of people may go through this phase at some point in their life, not many manage it well or are mature/emotionally healthy enough to make necessary adjustments to get through this without causing serious damage( though I’d say good riddance in those cases).
Here, this is what you find googling 'midlife crisis"](http://divorcesupport.about.com/od/isdivorcethesolution/f/midlifecrisis.htm)
• Unhappiness with life and the lifestyle that may have provided them with happiness for many years.
• Boredom with people and things that may have been of interest to them before.
• Feeling a need for adventure and change.
• Questioning the choices, they have made in their lives and the validity of decisions they made years before.
• Confusion about who they are and where they are going.
• Anger at their spouse and blame for feeling tied down.
• Unable to make decisions about where they want to go with their life.
• Doubt that they ever loved their spouse and resentment over the marriage.
• A desire for a new and passionate, intimate relationship.
Sounds familiar? Like I said, log off from gupshup and take him to counseling right away.
