Her friends are friendlier with me recently, could this be good sign?

I've been talking with a girl for some time and we still haven't gone out on a date, even tho we agreed to go on one (we were both busy with our studies). We have same group of friends and those friends are her closest friends. As we went back to classes, I've noticed that those couple of her closest girl friends are more comfortable interacting with me compared to past. I am sure she already know that I like her and my guess is those friends also know that, as I found out that she was talking with one of those friends about me because she knew something about me I told only to that friend (something funny).

So my question for you girls is, could this be a good sign that she might also like me as more than a friend or I'm way overthinking this?
