Where is this friendship going?

So, I kinda became close to one of my classmate because of our mutual friend year ago. But fast forward to 4 months she kinda became very close to one of the guy in our class , Now the problem is she kinda neglects us (me and our mutual friend) I mean she would hang out with him talk to him and comes to us only when he is not around or there is no one with her to accompany her. Over to it she will be draging us both to meet her crush and then she will be like " you guys just go I want to talk to him alone". She is even insecure because most of the time she will be like " you are looking way too hot , wear a mask or something in front of him or don't talk to him" . Everytime she will be talking about him non stop. Now today as well she started to be like" if you see him somewhere why don't you inform or why would he even see you" I just got so irritated that I burst out " that what is this, everytime he is the topic, you will just blabber his name the whole day, your life revolves around him" she said "okay don't be too loud and now I am not talking to you" Though I apologized to her over text but I don't know what's happening. The other friend of mine feels the same but she is not Frank in terms of taking a stand for herself. And wants to be in good books of everyone and she thinks that it's not worth it to make her understand. What is your opinion on this situation?
