My Dad left when I was 2 and I didn't see him again until I was 18.
We met up, he explained his reasons for leaving and I started to get to know him again (very tentatively).
It's taken us a decade, but it finally feels like a proper father/daughter relationship.
However, if on that first meeting it doesn't feel right, or even if the 20th meeting doesn't feel right – walk away. You should never feel obligated to stay in touch with someone because they are your family.
And let us know what you decide to do 🙂
