My crush lie to his parents and his father scolded me?

So I have been crushing on this guy for more than one year now, recently I left some gifts at his house (no one opened the door) and his father found them. When his parents questioned him, he lied saying that I was nagging him and that he was not interested. The following week I went to see him again, his father opened the door and when he heard my name he scolded me severely. Both his parents against me and then on a whim he rejected me saying that I have childhood trauma. He is inexperienced in relationship (27 and only one relationship) and immature. But what he did is wrong, I don't want to encourage his behaviour. what should I do, stick with him guide him and confront his parents (he has been living a lie since 2018 when his ex left him) or let go move on?
