You know your sons didn't take anything away, they added to your life. Your wife did. So your to blame too. 50% married couples, get divorced. So ask her. Don't take l don't know, for answer. Sounds like your done. If your done, do you want more kids by someone else, take care of yourself. Sorry 5 or 10 years not a long term marriage. At this point you and your kids come first. Well going to stick my neck out. When my heart stopped, wife called every one. Nobody calls family and friends when sex stops. Maybe if they knew, could help your boys. Stop the fighting and resentment, her dad could relate to this. My dad could. Go to work for you and your kids, have a net work for your sons. Nobody owes some one sex. Sexless marriage, there are people saying this is right. So it's up to you.
