From what i can gather, he does not outright hate his mothers support and love. You can sense it in his vague wording he gave to the student. He's just distraught that he's not allowed to do anything by himself, he wants his mother to trust him. This is also ultimately a journey for Sheila, Ryuuji and Karma. I believe at the end, they will end up pretty cool. This is very wholesome to me, i love this series.
