Pride. Apologizing can be particularly hard for men because it involves the admittance of fault. It’s hard to say that we messed up. That we were wrong. Our pride gets in the way.
Embarrassment. If we messed up royally, doing something truly boneheaded even though we knew better, it can be difficult to talk about it to the person we hurt or let down. We feel stupid and would rather pretend like it didn’t happen.
Anger. Things that need apologizing for are rarely a one way street (more on this later). We probably did something wrong, but the other person probably did too. And sometimes our anger over how they offended us is so great that we justify what we did and can’t get past it to apologize.
The antidote to all 3 obstacles? Humility. The reason we put up these walls is that we have an overinflated view of our true selves. We’re always right; we always have it together. But it ain’t true. We’re human. We mess up sometimes. You have to accept your imperfection as a part of life. Suppressing it will cut you off from others. Embracing it will allow you to grow as a man.
