Come with me down this rabbit hole if you will. The moment we the readers find out about how much Andrew cares is the moment he says "I hate you". Because of this one "throw away" line in the first book "I don't care about exy enough to hate it".
I personally think this is the exact moment HE relieved he was in love with Neil. Because he realized he does care, he cares so much it hurts. And he hates that, he hates his feelings, he hates the fact that Neil makes him feel- makes him care.
And so he hates Neil, because he loves him, because he wants him. Because he cares for him.
