Shall I ask my dad if I was the reason he left? Listener question

I’m leaving in just over a week to be with my dying dad. He left us when I was 6 and I didn’t see him again until I was 31.Something I’m aware of is a programme acquired around not being enough and things being my fault and I’ve wondered recently if this comes from a small child’s mind creating associations and innocent beliefs about that situation.I would like to directly ask my dad if he left because I wasn’t good enough or whether I did anything wrong. I feel that perhaps hearing his response will bring more reality.But I don’t know if this is just a separate self seeking more security.Any thoughts would be so gratefully received.
