I think that I might have to go against the crowd here. Call her if you want to.
Only you know what is appropriate and what is not. Everyone have different relationships and there is no reason why you should completely cut off somebody who used to be so close to you.
Anyway, I had two long-term relationships (2 years and 3 years) before my current bf. One of them is still one of my best friend (3 years) and I no longer talk with the other one, nor do I have any interest to call him.
IMHO, I believe that each relationships are different that you shouldn't treat them the same. I think you already know that you should call this girl or not. My only advice is, if you decided to call her don't be upset if she doesn't want to talk to you. It could take a lot of time for both of you to get over one another, and it is usually much longer than you think. For me and my 3 years relationship, it took us about 6-7 months to be friends again. And it is different for everyone.
