Hello J.
I am sorry that this is happening to you.
It sounds as if this girl has a lot of problems, and, as you know, people in their teens are changing all the time.
Do you think that things became too serious too soon?
You cannot change her.
You can be supportive, but you cannot take responsibility.
As you know, things can become very complicated at times.
Personally, I think that sex makes them even more complicated ~ whatever one's age.
Take care
