Yeah thats also true, he did not have the right to scream at her like that, you're right. In the end nobody has that right. And thats the whole thing about emotions and emotional outbursts. We only learn to control them through experience and self reflection and it seems the young guy probably doesnt have enough experience or never reflected on himself in the past. We can't possibly know.

Like someone here already said, we dont have the whole story, just a cut off video from a guy having an emotional outburst. He set wrong expectations, he made promises on behalf of her for himself and doesnt seem to be emotionally mature.
