Scorpius
I'm sure it wasn't easy to raise a child on his own and I'm sure when he looks at you, he see's your mother as well. But I wouldn't believe that you would be a burden.
Our family hasn't always been the most forthright in emotions, so I'm sure he wasn't very good at explaining or helping you through the situation either.
Whenever you want to visit Scorpius, you are more than welcome to.
