What happened to men who actually commit?

Was at my son's baseball game and overheard a couple of dads talking about bailing on their families. Divorcing, moving on to younger women, the whole thing. Made me sick. When you make a vow that's it. That's your word as a man. Doesn't matter if it gets hard or if someone cuter comes along. You made a promise in front of God and witnesses. I think we've lost sight of that. A man is only as good as his word and his commitment to his family. Everything else is secondary.
