Tom and Katie are divorcing. Evidently Tom did not see this one coming: Katie filed in NY where the records are sealed, so we will probably never know the details. I feel sorry for Tom.* I think he is sort of a control freak, out to prove something - like his manhood. Why else would he endanger his life doing all his own stunts? It seems to me he pretty much obtained the marriage he contracted with Katie - he wanted it - he wanted her. Secular-civil marriage is a form of acquisition and possession - on one level it is a means to contract, or claim ownership of one or the other, or in today's terms, one another... it becomes a legal claim of possession.
In the old days especially it was like that - consider how the woman lost her identity and became known as Mrs. John Doe - not Mrs. Jane Roe-Doe, but Mrs. John Doe, or Mrs. Doe. What happened to Jane? See what I mean?
So Tom Cruise is actually an old fashioned kind of guy - he goes looking for brides, buys them, and then they leave him. He might just be too possessive... although he's obviously a good provider. Ka-ching.
Anyway - in our day, marriage has lost its meaning, don't you agree?
*I feel especially for him because despite all his fame and fortune he strikes me as terribly unhappy and shallow.
