I hope your wife feels better. I think that we all made mistakes and hurt others along the way. What we can do is being better today and tomorrow. Resentment, anger and regret are not good companions. I think it shows maturity to admit to have been hurting someone and to have the courage and humility to admit the personal mistakes. I have found that it brings a lot of peace to apologize, even if you don't get the same in return. Some people realize later in life how much damage they have made. And it's better late than never. Thank you for sharing this!
