Today a part of a song popped into my head: "I wish I never met her..." from a jam by Carl Thomas.
Watch "Carl Thomas - I Wish" on YouTube
Now I have never personally dealt with the married woman situation, but I've had a few personal situations where I was attracted to females who had boyfriends out of state. (You could not tell by their actions until they revealed the secret.)
And just like poor Carl, I could see the "I want you" in their eyes. For us males, this does not bring out a creepy tingle; just a huge ego boost.
Now as this song came to mind, the Spirit quickly interjected in regards to the songs intent. The real sadness is that there was this quick jump into physical matrimony and a giving of the heart prematurely. [Numbers 15:39 reminds us how our hearts need to be examined constantly.]
I too have done the latter of the two, and this is why many our our past situations hurt us so bad. But there is hope for the hurting heart.
Psalms 27:13 I would have fainted, unless I had believed to see the goodness of the LORD in the land of the living.
27:14 Wait on the LORD: be of good courage, and he shall strengthen your heart: wait, I say, on the LORD.
We just need to spend more time waiting on God, than wishing we hadn't made mistakes.
