I have been reading some posts from sites like this where wives that say they love their husbands but cheated or love their husband but are thinking about cheating --

I am 60 years old and my first wife cheated on me within 6 months of getting married -- we had dated on and off for 4 years prior to that. I was young and stupid and looking back should not have gotten married that young but I was in love and she said she was too. 

I won't go into the details of what she did but I can tell you even 35 years later it effects me and I can't see a movie where a loving wife makes a in the moment  mistake and cheats on her loving husband that I don't get so upset I almost scream at the TV --I don't under stand how anyone man or women could say you love your mate and could not live without them but yet still cheat.  The pain I felt back then almost killed me and took 10 years to find someone I could trust again and marry. 

You need to talk to your mate and tell them if something is wrong and keep telling them instead of cheating and then making a excuse .  Any for not telling after and saying you will never do it again --He will find out believe me -- you will act different and it will eat at you and then the lies will make it 10 times worse -Don't do it !!

Make him listen or seperate first -don't become a cheater -you will never be looked at again by him the same way -He might say he forgives but he will always think about it .  It will destroy him and like me it will hurt the rest of his life like it happened yesterday.
