The predictable lib response: "Oh, no, Andy, don't feel bad. There was nothing you (or any of the gazillion absentee fathers like you) could have done." This, of course, is a huge lie, but it makes libs feel better about abandoning their own kids.
'I was not there to protect you.' He is right and he does bear responsibility in this -- and he knows it. Shasta's dad was not there to protect her, either. Non-custodial is a legal determination only, not a moral exoneration. Dads DO protect their families physically; when the parents split up, the children are left unprotected. Biology is unaffected by Political Correctness, sorry.
