This situation remind me of BG Alex, the top had to treat the bottom badly before realizing the feelings he had. I think it's a wast of the time they could've spent together, loving each other.
In any case, I do not want to take the top's defence here but it is very difficult and almost impossible to overcome a trauma that we experienced as a child. Knowing that he saw the corpse of he's mother, that he tried to resuscitate. And on top of that since he's a little boy his grandpa told him to not trust anyone.
''Ceci n'explique pas celà'' but we must try to understand the two parties instead of condemning him without giving him the benefit of the doubt.
Hope that he won't get rid off the poor baby if it get a nuisance for him
