One thing everyone needs to consider.. In this day and age if your spouse cheats on you he can bring home something that will KILL YOU.
On top of the blow to the non cheating partner's self esteem, the cheating partner can, in addition to all the other miserable behavior associated with addiction, give you a death sentence.
I am sorry but that is the truth.
I will never tolerate lies and cheating. Of course if I had known he was using all those years he would never have gotten 6 years out of my life AND put me at risk for disease. but.. I naively believed him and it was all a lie.
My Dad always said if a person would lie to you they would steal and cheat as well. His attitude is at the first lie he was all done with that person.
I lied to my Father one time when I was 12 and he found out. It took me YEARS to earn his trust back. If I had taken the same attitude with my X I would not have to wait until June to get another blood test to make sure I don't have something deadly.
My life is worth too much to me to risk it with some guy who cannot be loyal.
