Need Marriage Help

(Atlanta, GA )

Need Marriage Help: My marriage has fallen apart. My husband was a great father and a great husband. He is almost 40 and he has lost his mind. He travels for works , but the past year he has been absent. He still comes home for family visit and he's there for holidays, but that's it. He's no longer here for children activities and he has missed their birthdays also. There is another women involved. I'm just tired and ready to move on , but something keeps holding me back. I did not grow up with my dad and I'm afraid my kids will lose their dad. He calls them and he sends support payments sometimes, but the man I knew and loved ran away and I'm confused. I'm tired and ready to move on, but I'm afraid for my kids.
