Is OTHER wrong in the post ? POST : Throwaway for obvious reasons.

My former best friend and I have been friends since college, about 9 years now. I have also been friends with her husband since then as well, as I met them both at the same time. I've been through a lot with the both of them; I was MOH at their wedding, she was MOH at my wedding, I've been their through my friend's DUI and legal troubles, etc. 

Since my friend got married to her husband in 2013 she has been pretty flaky, and it's only gotten worse with time. She doesn't answer my texts or calls, sometimes for weeks on end now these days. However, I have always made myself available to her, no matter what time of day, for her phone calls or texts; I always answered right away because I loved and cherished her. She's done some pretty awful things in the past that I've forgiven her for. For example, at my wedding she had to come stag because her husband could not afford to fly in along with her, and she was pretty upset at the idea of 'being alone' during the reception. So, after the dinner at my reception was over she invited some man I've never met to my wedding to hang out with him as her date (she was in an open marriage). That is just one example.

Her life has been on a big downward spiral since 2014-2015. She was an alcholic, got three DUIs and went to jail, has jumped from job to job, and is now going through a separation/divorce with her husband, who I am still good friends with. Not only that, she's had some physical health issues, and has struggled with depression. She recently went to rehab for her alcoholism, for a whopping 45k, which her parents paid for, as they have for nearly everything in her life.

My breaking point was when she ghosted me on a text after she told me she'd gotten into an argument with her mother, whom she and her husband have lived with multiple times throughout their marriage, and she was going to sell all of her things to get a plane ticket to fly back to the state I currently live in. I told her politely that I thought she was acting rash, and that she ought to take a step back before doing something like that. She never texted me again after that. I had to text her husband to find out that she ended up getting the ticket and flying halfway across the US to my state, and that she had already landed safely and had somewhere to stay. Then after all that, two days later and still no text from her, I get an email that she had logged into my hulu account. I was livid. I booted all the devices from my acct and changed my password. 

Since then she has texted me twice; two weeks ago with a Rob Lowe meme, and then a few days ago to brag about a kitchenaid she got for her bday. I ignored her texts. My mom says I should at least be cordial because friend knows she fucked up, but I'm through. My friend hasn't asked me about myself or how I am doing for the majority of our phone calls/texts for the past year. 

AITA?
