Input: A little backstory for context, my best friend and i have been close for about four years, and things started turning sour around this time last year. 

So for a while I was living with my best friend (bf for short) and her family, and I didn't have anywhere else to go. All was well until she started seeing this guy, and it really got bad. 

The first time was when I bought train tickets for bf and I to go visit a friend. We were only there for about an hour before she had her boyfriend come pick her up, leaving me stuck there by myself until the train came a few days later (I had no option to leave with her, his car only had two seats). 

So I ended up staying up north for a while, and while I was gone her boyfriend stayed over for a while. Once I came back, he just never left (keep in mind we were sharing a bed so this entire time she made me sleep on the couch). 

A few fights later and a months worth of sleepless nights on the couch, I decided to move. After a while I ended up forgiving her, and all was well. Recently she was going to come visit me for a week but ended up canceling on me because her boyfriend was coming to town, and I just decided that I was done dealing with her doing that kind of stuff to me. AITA?
