The other side....
I've read the preceding comments and I wanted to present possibly a different view.
I'm a very frustrated husband. I've been married for 41 years. My wife and I separated two months ago...for the second time in the past three years. She believes that I am bipolar although I have never been diagnosed as such. I do have mood swings, but not cyclical. I have to ask, "What separates severe frustration from bipolar disorder?" Are your husbands "simply" suffering from "extreme" frustration with elements of their lives...their marriage to you? Their job? Their success or lack thereof? Their income? Their role as the "bread winner?" Etc.?
Personally, I am frustrated with my marriage. (After 41 years, you would expect a common and sustained level of love, appreciation, and respect...but we don't have that...and that frustrates the hell out of me.) We're getting older every day; our lives are rapidly eroding with age, and instead of “investing” in our marriage and our family, and growing old together in each other's company, my wife wishes to spend time debating whose fault something was four years ago!
Hello, husbands, sound familiar??!
Look...we all have mood swings. Given the economy and other life pressures, it's a wonder any of us remain sane! Further, our view of the world changes as we mature. And we all make mistakes along the way. We're not perfect. But if long-time married couples lose focus on the future....of a "common" goal, or fail to "invest" in their marriage, then every little issue becomes magnified over time. You grow apart. You have different priorities. You withdraw. Communications wane. This creates an open door for depression, for infidelity, and for disppearing love and respect.
Yes, you can point fingers and call it a bipolar disorder...but what if you're clinically wrong? Are YOU simply seeking an EXCUSE for your own marital short-comings?
Although I am NOT a doctor, I would submit that many "BD" situations are not really BD, but simply imbedded frustration that has metastasized.
Consider this input for what it's worth....
