Toughest decision I ever made was to walk away from the cheating mother of our two children. I tried for 2 years to get past it but couldn't! I went down a bad road afterwards and it cost me dearly and the worst part of that was that I knew it would. All I can tell you is that life get's much better and if you stay in their lives the kids adjust. It sucks but they are all that matters now. I didn't get married and have children to become an every other weekend father and I fought it as hard as I could but jealousy and the devil ate me alive and dang near killed me. Keep your head up and know that if you are there for them they will know and the circumstances will even come to light eventually in their eyes. For me the light at the end of the first tunnel was a train but I survived and found my way to the other side. A bitch like that won't make it easy on you but as the kids get older and see that their father never gives up, and they will, they will have that much more respect for you! Life will be much better! I will say a prayer that only folks like us can understand for you!
