Hair problem ar. Me and my ex also got this problem.

Fact 1: Short hair easier to manage
Fact 2: The hair doesn't belong to the guy
My ex know I like her long hair, some times quarrel sure
threaten cut the hair because she know it's some thing that I
like.
Love problem very complicated one. But if I were you, I'll tell
her "Go for the hairstyle you like and finds it comfortable"
