From the comment about cheating ("that would have been a lot more fun ugh") to the comment about how he became a "super helpful husband with the divorce" once he realized he would be a millionaire, the post gives the impression that the OP was all about himself and never truly cared about the experience and feelings of the woman he was married to.
On the plus side, at least the OP realized that he didn't want to be married and didn't make the same mistake twice.
