Trish, At this point, she doesn't sound like much of a friend. I think what happenned is that you graduated highschool, you grew up, you changed you life, and now have something good, Husband, kids, job, things you enjoy. She hasn't grown up, she hasn't changed, she is still in highschool, and doesn't realize that no one else is. Unless she miracualously grows up, your best bet will be to let her go, and hopefully, you will find someone else you can have a close friendship with.
