If a woman wants to break up, she will always find reasons or make them up!
Her reasons are usually very simple!
She takes distance because she has another man in mind, wants her freedom back, can't deal with tensions or simply outgrows the relationship.
Very often she won't tell you why she breaks up.
She will invoke something you did 3 years ago or an aspect of your personality she no longer likes.
Why won't she give you her real motives?
Because her inner motives are part of her battle plan.
If she unveils them to you, she opens up emotionally to you and that's the last thing she wants when she is trying to get her freedom back.
To your power!
