I cant comment on the relationship side of things, but as a kid from a broken home, my parents split up and my Dad moved to the USA a couple of months later and has been there ever since. I see him on average once every 3 years maybe. I used to speak to him every Sunday night on the phone as a kid. Now i Face Time him once a month maybe. I have to say it had ZERO negative impact on me growing up - my mum replaced him within 12 months with a step dad who is awesome. He's not better than my Dad, just different, and i wouldnt have him in my life if my Dad hadnt left.
