Divorce..venting

Well I guess it took us a year after his cheating to realized divorce is what we have to do. Well that's what happens when you cheat. As much it hurts me I have giving up. I just don't understand how man or woman can choice to cheat knowing that will be the end of their marriage. How can you love someone and cheat on them and expect to stay married. Was it worth it? Was she even worth ruin a marriage? Were did all the love we had gone to? Even when we both agree to get a divorce it still hurt..😭 The only thing that sucks is the kids pain they will go through.
