When things get rough, I sail away

In 20 years of existence half of it was unsupervised by my parents. I grew up with my relatives, with my siblings, and with a maid to fill in our parent's absence. I understand that they have to earn to provide us a life better than what they had. I get that part. But the distance between us grew, as I grew up. What I don't understand is how it happened? I just know that some point in our lives, all of us stopped caring.
