2. “Is it that time of the month?”
It does not matter if you mean this in a nice way or not, this is a question that should be avoided at all costs. No woman likes to be reminded that she can be a bit of a pain during that special time each month, especially not by you. This is a question that should only be asked if you have no fear or basic intelligence.
3. “You should calm down.”
Ask yourself, has telling someone to calm down ever actually made them calm down, or did it just make them angrier? 99 times out of 100, it’s the second option. Put yourself in her shoes. If it was you that was upset about something and she told you to settle down, you’d probably lose your mind. So give your girlfriend the same respect and let her blow off steam.
