AITA for my friend ghosting me

My friend cut me out of her life out of nowhere and I don’t understand why. I (34F) met my friends bf (31M) first over 10 years ago and then he started dating someone who turned into my bestie (38F).

My bestie that cut me out of her life had hit her rock bottom in life. As a good friend that I am I would always let Sarah (names have been changed) know that she has an open invite to come over and be able to shower, laundry, I would give them snacks to take with them and cook for them when I could, given her some clothes to help keep her warm on the colder days. Just for context I live in a studio apartment and I have a couch that pulls out so they have somewhere to sleep. Not a huge space but given how long we’ve been friends for it’s like a sleep over but with friends as adults. This past year over having them over we grew so much closer as friends than ever.

Now, every time she’d take a shower she’d always let the water run for an hour every single time, yet Whenever her bf Ryan had a shower he would only be in the shower for 10-15 minutes, so I casually brought it up about letting the water run that long, she took offence to it by the way she was reacting to it and wasn’t really speaking to me the rest of the night. She went to her car and was in there for probably around an hour claiming she was looking for a brush, seems weird but okay. I never once said she couldn’t have the shower it just felt to me like she wasn’t being considerate given how she’d let the water run that long every single time..

As the laundry was done she randomly decides to turn the dryer back on at about 4-5 in the morning…. I was having one of those nights where I couldn’t sleep and was getting a bit of a headache and turned the dryer off as there was no need to have it on either way.

When we were all up in the morning she was like a bat out of hell wanting to leave, as I was outside having a smoke she got all her clothes out of the laundry and the rest of her stuff together. As I came back in she darted outside telling her bf to get the car. When he pulls the car around and get the stuff in the car he asked what was wrong because he had fell asleep early and had no idea what was going on. I’m like I don’t know whatever it was it was her and the fact she wouldn’t talk to me. She left my place that day without saying by to me or my cat….

Later that day I msged her bf asking if she’s alright, the only response I got was ya she seems fine now. So I waited a few days before reaching out and asking her what happened, and can we talk about it so we can move past this. No response, no surprise.

Now her bday is the day before mine and as a bday gift I bought her and her bf tickets to see a comedian that was going to be in town the same week as our bdays so I thought that would make a great double date bday outing.

Now that it’s been a month since she left the way she did I decided to send one finally msg. In the msg I was asking what I did that was so wrong to make her react like this and why she couldn’t even give me a reason even if it was some bullshit lie, cause I just wanted to talk it out to see if we can be friends again cause to me it felt so petty to get this behaviour from them. I even brought up the tickets and how I don’t want to have to give the tickets away either. Again no response.
