I logged on for the simple fact of trying to understand something.
I am in my mid 40's single and have been dating a wonderful woman for almost two years now.
Problem is her daughter.

She is almost 16 and acts very immature.
She is always doing things that make no sense like squirting the entire ketchep bottle on here fries and then gets mad if someone says something about it.
She will take her food and just smash it up and mix up everthing into it that she can find and then eat about half of it.
She also dresses and acts like a boy, totally obsessed with hunting and fishing.
She also has trouble keeping friends I guess because she is not girly in any way.

My question here is will she grow up eventually?
I thought at her age she should be more mature than she is.

any advice is appreciated
