Opinion That can create a sticky situation. What is the relationship like between you and your husband and his ex wife? How is your sister-in-law toward you? Is she thoughtful and considerate of your feelings? Initially I say that as an adult, your sister-in-law can choose her friends without anyone's approval. But, as an adult she should be responsible in her decisions and be thoughtful and mindful of the complexities that her friendship creates.
Opinion
You should discuss the situation with your sister in law. You haven't mentioned if there are children involved and whether a problem has been created by her being invited to family gatherings. Also, the feelings about each other between all the parties have not been defined.
If your sister in law has simply maintained a friendship with her former sister in law then that should not be a problem. A divorce need not affect every member of an expended family. That would be childish. If there were particularly hard feelings between the divorced parties then your husband should be the one invited to family parties. His ex wife is no longer part of the family.
It is still possible. Since you two are still friends then yes, it's a possibility.

If you were good friends before odds are that you will still be friends now but if it has been many years since you have seen each other and you barely remember anything about them then you probably aren't as close as you were before
Since the academy and they still are. Although Sasuke and Naruto don't really admit it. They really are still friends no matter how much they fire off punches.
IM not sure if they are still friends or not. But i think they are .They knew each other ever since the 9th grade.
No, they were never best friends. Selena Gomez has always been best friends with Demi Lovato, in fact they were best friends since they were 7 years old.
Yes. They are all still friends
That probably means that she still cares for you and she just wants to be good friends.
