That is a loaded question. I do not regret that I married at all, and my spouse and I have a lot to be thankful for and an lot of good things have come out of our marriage. What changed over time is that we have different interests, especially in the intimacy department.

That lead me to look outside. I am not open about it, but I am pretty sure that my wife knows that something is going on, but does not really want to know.

Yes, sometimes I wish I were a bachelor again, but this desire is short lived when I am reminded that my spouse and I are really successful in almost all aspects of life short of longing to be intimate again with each other.
