<human>: Give me the gist of the text in a nutshell

Due to reasons I won't bother to go into in long form.... I don't want to be her friend anymore. Long story short, sometimes she uses me and sometimes she's really mean/offensive to me. 

So I thought I'd just avoid her and slowly drift away but she's been texting me stuff like "you suck" and "you're a terrible friend". Then a few months go by and then she says, "Wow you are a terrible person". At some point I felt guilty so I replied her about why I was avoiding her. Partly because I felt like I couldn't fit in her description of a friend, so I thought maybe she would be happier with her other friends. Since, I go to school, have two jobs, etc... I'm rather busy and she doesn't seem to understand that aspect. Although usually I try to make it up to my friends by fitting them into my schedule and she thinks I'm selfish for doing so. Essentially "doing everything I want to do" and nothing she wants to do (which is untrue. I will do what she wants if it fits into my schedule). Anyway, I got busy again and I didn't have time to schedule a day to meet with her. We were friends for 8 years? (Since High school. I am now about to graduate college). 

She sent me this fb message: 

"I knew u were a bad friend but I didnt know u were a bad person... Ignoring a problem doesnt make them go away. But in this case ignoring a person will. I cant continue with someone who clearly doesnt care at all... So cya when I cya." 

I don't really want to be friends with her anymore. What should I do? Should I just block her on fb and continue ignoring her or should I confront her?
<bot>: Don't want to be friends with someone anymore. Drifting anymore. The friend still wants to hold on. What should I do? We were friends for ~8 Years. She's 21 and I'm 22.
