The last of the contraband

I have finished the last book of contraband that I got at the library.  This was an interesting look at a woman who runs into an old boyfriend and reignites a friendship with him all the while trying to decide if she is really happy with her marriage. 

Maybe its just me, but why in the world would you even bring that trouble into your life.  In my mind, if you are married, your choice has been made.  Toying with an old romance whether mentally, emotionally or even physically is never a good idea. 

The character did not technically "cheat" on her husband. But in my mind, the emotional energy she invested in this other man is way worse than any physical manifestation.  It was okay, not great.
