When you ask for change, suggest small improvements. Ask for what your boss can realistically deliver. Nothing works every time. In some cases, your boss may grumble and appear more upset. He or she may need to ponder on your input or suggestions.
Some people like to mull over issues before they wave the white flag.
A boss who is very emotionally cold may not soften up in front of you. The softening up may come later. In a worst-case scenario, it may not come at all. If your boss meets you halfway, you've scored points in the game of life. You've taken control and eased a bad situation.
