Dragon hid Luffy in the East Blue and stayed away from him because he didn't want Luffy to get dragged into his revolutionary conspiracies and be captured by the World Government.
He somewhat recently reflected that having personal relationships are liabilities for leaders when Ginny was taken from Kuma.
Since we now know Ginny and Candel were sexually violated, and that it is very likely both Viola and Lili were also violated, the idea that Dragon's relationship partner (Luffy's mom) was also violated and likely killed because she hasn't appeared in the story has become likely too.
She's either really well hidden like Luffy was or she's dead. That's how I see it.
