Is it good or bad for a woman to be too rational?
There is nothing wrong with reason, it is human nature to analyze the pros and cons before doing anything, so rational girls can always control themselves and not be led away by scumbags and not be hurt.
But it's not good to suppress yourself. I guess the repression you are talking about is that you are not good at investing in feelings. But that's nothing. It just means that you haven't met someone who makes you particularly excited.
The world is so big, there are so many people, there are very few couples who can meet and sincerely cherish each other.
So don't always reflect on whether you are bad or not, please stick to your reason and firmly believe that you are right. It's much better to have faith than to doubt yourself.
