I would not get near my ex-wife with a 50 foot pole (literally or figuratively, if you know what I mean) .. She's still attractive, still looks very nice physically but she's one woman who has the mental characteristics that clearly reminds one that, "all that glitters is not gold." That is the one lesson I learned from our 6-year marriage.
She's married twice since our divorce 13 years ago and is on hubby #4. I was her 2nd husband. I've only been married once. My experience in that one marriage has made it extremely difficult for me to do it again, and I doubt that I'll ever remarry.
Why? Because, over time, I've enjoyed raising my kids (I was awarded full custody when they were 3 & 4, now 16 & 17), have become somewhat set in my ways, can watch football all-day Sunday if I chose to do so, and there's some credibility to the adage, "why buy the cow when you can get the milk for free?" This can be accomplished by telling women the truth about your intentions, and by protecting yourself from fathering children out of wedlock and STD's by using prophylactics.
Fortunately, my ex relocated to another state about 10 years ago, a couple years after our divorce, so we rarely see each other. Even though it's been 13 years, I am still very uncomfortable being in the same room with her.
