There was a point in time when this was acceptable-for men to have a mistress. Its called the double standard. The truth sets you free, so be glad that in this area our society has matured to the point where this is no longer acceptable.
This happened to me when I was 30 and had three children. I am now 58. My children are responsible adults, are all Catholic and I can be proud of their achievements. I am living a chaste life according to my station in life, and you know, I never knew such joy at any time during my life. My children learned to accept their father’s behavior, but did not condone it. My ex passed away six years ago from a viral infection. I cried for weeks-still loving him as I did. But God will fill those wounds with his Love.
My prayers are with you during this terrible and painful time. Put yourself in God’s hands, through His Son, Jesus Christ and the Holy Spirit. I continue to say that frequently, please try this and watch how your thoughts change, how calm you become, and how joy will enter your life in very unexpected ways!
