Have you ever "broken up" with a friend that was within your close knit friend group?

Trying to keep this brief: I have a tight-knit group of four friends from college (over 20 years ago). We take a girls trip after 2 or so years, and it is always one of the highlights of the year for me.

I want to "break up" with one of them - but how will that affect our friend group? I was closest to her, but we also have a history of some fall outs. She is very aggressive and I am conflict avoidant. She has always been inconsiderate and self-absorbed and took me for granted, and I have always been a people pleaser (due to a narcissistic and abusive mother) and let it slide. I am also finally older, wiser, and have a low tolerance for people who don't follow the golden rule.

Recently, I moved across the country and hosted her and her daughter for a weekend this summer. There were numerous rude things she did, such as make me wait almost an hour past the time she said she'd meet me to pick her up after driving for over an hour to meet her there, complain about the air mattress bed we deliberately bought for her and her daughter before the stay, deliberately wander off when we went to the mall to kill 30 minutes before the pool was open and when we found her and her daughter, they wondered off again to "buy socks" when we were walking to the car. We bought them a nice dinner and my husband ran out to get bagels in the morning, and we paid their guest fees for the pool. I then drove them to the airport. Her daughter was also bad mannered - left pee all over the toilet, took out a box of strawberries and started eating them and throwing the tops back in the package, kicking my younger son in the back, and walking on our coffee tables, amongst other things.

Although we didn't say anything, it was probably obvious that we were getting annoyed. After they left, I never got a text or call from her thanking us for our hospitality. I haven't heard a peep from her and I haven't called her either. We usually talk every other day, and it's been over one month.

What did you think happened on her end? Should I try to reach out an olive branch or let her go? I am most concerned about the dynamics of the friend group.
