I need some friendship advice

Okay I sound like a teenage girl but I’m 24 years old...

Basically I’ve been friends with this girl since 2nd grade. We get apart here and there as we went to different colleges but were from the same home town and reconnected along with another friend about two years ago. We would all hangout and what not UNTIL... recently she just completely dropped us. We would ask her to hangout and she did get a boyfriend which I totally get and would just never make the time or put in the effort for us. Now, she’s had PLENTY of boyfriends in the past and we’ve gotten to know them so I know that isn’t the issue.....she just stopped talking to us. I would always say hey wanna come out with us? And she would go, “sorry I can’t John and me are doing this” “sorry I can’t I’m going here, I’m going there”

NOW, I KNOW that we are grown women and we are all busy. Trust me I have a full time job, a part time job AND I’m in grad school. But to me, my friendships are the MOST important thing along with my family. I don’t have a boyfriend so I don’t really have that. I DO NOT take my friendships lightly, each of my friends are shining stars in my eyes and my sisters. I also can time manage pretty well and will MAKE time for you. So LADIES, my question is......am I being over dramatic? I mean we’ve been friends for years soooo why are you gonna drop us for no good reason? We did nothing? And why act like you’re better than us?? I mean yes, I am a little hurt. If she had a reason I get it........but we have always been so close????

I know people come and go and people move on but damn!!! That shit hurts
