Do you think i made the right choice?

So I known this friend (well, ex-friend since August 26th. she's female like me) ever since I was in elementary school. I recall her getting me into trouble a lot and she could never be as much of a friend as I was to her. I acted out growing up because I was angry and frustrated with her so this wouldn't be the first time I cut her out. All I wanted was for her to be a actual friend to me. When I moved from my state, I haven't seen or spoken to her in 4 years. Not long after I found her again on Facebook, she kept telling me to get this money from this agency but I didn't want it because I thought it was a scam (you had to pay money to get money).

She got mad at me and said "you don't trust me. bye" trying to leave chat. Not only that, but she also accused me of not being me even though my profile was as obvious as it can be. It really hurt my feelings. So I ended my friendship with her because I was living through the false hopes of my dreams that she would change but the truth is that she won't. I'm trying to reassure myself that I did do the right thing and that if she could change, she would've done it growing up with me.

This is sad to me because I've known her for so long but I didn't have a choice. It was a unrequited friendship.
