He has a resume of responsibility
Having kids is the biggest responsibility most men will ever be given. Responsibilities are like steps. The more he takes, the better his balance. But he has to crawl before he can walk, then maybe he’ll run so fast you’ll get whiplash.
A guy that’s ready for kids is no stranger to responsibility. He’s taken those steps, way beyond what it takes to be self sufficient and spends most of his time managing the affairs of others.
He’s not perfect and mistakes come with the territory. You don’t acquire gymnast-like balance without fumbles, but he honors the commitments he makes with family, friends and colleagues.
