I don't think Gi is bossy,she just love talking without nonstop!
remember when Leo said that that main reason of their good relationship was their friendship,he said that first of all they were best friends and it helped a lot,I believe,that the only reason of their break-up was Leo,cuz he wasn't ready for family,Gi forgave him soo many things during that five years,we all know he he's womanizer.as she said she felt very bad after their break-up in 2002 and her heart was broken.Leo wasn't a as he is right now! if Gi was bossy,I don't think their relationship would go on for five years!
