Once again, let me reiterate what I see in my practice on a more than occasional basis: 40, 50 & 60ish women who tossed out the original hubby because, "the grass was greener". This is a nebulous statement, however, I have come to understand that it means, "a new lover", "a richer man", the potential to have a string of lovers. fun times, and the best one I heard, "I was scared of getting old and regretting". They figured there was a pool of guys just waiting to sweep them off their feet, or they had gone to another guy.
Then reality sets in. Could be a year, could be five. They realize that the marriage was not even one tenth as bad as they made it out to be. Some come running back to hubby if he will have them, (one is five years and ten guys down, she asked hubby to come back, he replied; when you left you were my wife, now your just a used up old *****.) Most have had hubby go off and find someone else. Some have mental breakdowns when they hear hubby remarried, because somewhere in the back of their delusion was the thought that they could go off on their own and then hubby would be waiting...no dice.
Canada, a better life awaits you. Do not be surprised if she shows up on your doorstep a year or so down the road. My BF is on his third. His first admits that she thought that he'd be around after she went on her voyage of "discovery". She wrecked the guy, he moved on, first with a short rebound, and finally with the woman who has been his wife now for 20 years. At their daughter's wedding, when the parents danced, she had nobody. It was actually painful to watch.
