I (29F) known my ex best friend (30F) for almost 20 years. Throughout our friendship, this person has cut me off about 3 times. The first time they cut me off, it’s because I didn’t want to house a mutual friend. The second time it’s because I apparently wasn’t spending as much time with them and the second time they cut me off, I literally had knee surgery a couple days after and they didn’t even check on me or visit me while I was on bedrest. The third time they cut me off, it’s because I told them to meet me somewhere and they went but I ended up cancelling on them so that was understandable. They decided to write me in the beginning of last year and we became cool again. One thing about this friend is that they would ask me for money every now and then and I would give it to them because I kind of empathized with their situation, how they don’t really have anyone and they’re in school. Last summer, they introduced me to someone. They kind of urged me to get involved with this person. I started to mess around with this person and this person turned out to be messy. I went to Europe for my friends birthday even though I didn’t have any money to go, I had to ask my mom for money to be able to go because my friend was turning 30 and I wanted to be there for them, especially since they kind of guilt tripped me into going. I went, spent $1500 of my mom’s money to celebrate this person. Cut to 2 months later and my friend basically put me in a group chat with their partner and gave me an ultimatum basically telling me it’s either I choose them or the person they introduced me to. I essentially chooses the person they introduced me to but it’s only because while me and my friend were texting, the messages weren’t being delivered so I assumed they blocked me once again and panicked and blocked them back. They wrote me through over social media platforms telling me that I’m a horrible friend and they were there for me when I wanted to kill myself. I brought up how I was always there for them in terms of providing financial assistance whenever they asked and I don’t know if they ever got to read that but I wanted to know, did I make the wrong choice of cutting this person out my life or am I an asshole?
