Maybe he keeps changing, not as soon as you come up.

It seems that you care about him. This profession is very important to the boy. Maybe he is really unhappy at work. Although he ignores you, it's not because of you.

Of course, the clearest thing is yourself. Give yourself more confidence. Don't worry.

Also, if he doesn't want to be with you because he is bored, then give him up as soon as possible and start a new life, so that he can live a little easier.
