One similar experience i had when I was starting out was when I created a PR and my colleague instead of suggesting changes, made the changes himself, approved and merged my PR. I told him directly that it’d be nice if he’d have suggested the changes instead of making them himself. He thought I was being protective of my code. I was never able to have a good working relationship with him anymore and eventually left.
