The trouble with this theory, however, is that any evidence of bridal blues in my wife's case has little to do with such psychobabble, rather being entirely down to a series of spectacularly bad decisions on my part - in particular bad financial management - that would test the patience of any 21st-century bride, or one from any other epoch for that matter. Ask any alpha-male trader or fund manager who depends on being in the 'zone' to perform well; when your confidence or judgement goes, it can make you depressed. After a series of spectacularly bad calls that cost me tens of thousands of pounds - such as driving my BMW 740 around without coolant in it, despite the red warning light, until it blew up on the M40, or choosing to gut both my London flat and country house, sending in two teams of expensive builders at the same time without having a proper budget in place - I went to see my doctor, saying I didn't trust my own judgement any more. My decisions were becoming increasingly irrational and self-destructive. What had gone wrong? I had a beautiful, smart wife, whom I loved madly, and Spear Media, the wealth management publishing house that I founded five years ago, was prospering with new editions around the world. How could I be suffering from the groom blues?
