I’m desperate to show my children how much I love them after walking out on them 30 years ago

DEAR DEIDRE: HOW do I undo the damage I caused to my children when I walked out on them 30 years ago?

They now have children of their own, who I’ve never seen, and my heart is broken. I’m 72 and my four children from my first marriage are now in their late-30s and early-40s.

My ex-wife and I divorced over 30 years ago, when my youngest son was only five years old.

At first, I had joint custody of my children, but their mother used them to control me and it took a toll on my mental health.
