What makes me a bad friend:

According my my 'best friend' it's this:

1] telling her I think it's a bad idea to talk to her ex because she got really hurt last time and started cutting herself really badly.
2] joking around when she mentions said ex (which is in every conversation)
3] having never been in love so I can't sympathize with her
4] making new friends
5] bring her to concerts and not getting on her case about paying me back

I just want to know,
does that really make me a bad friend?

Because, you know, I thought that as her best friend, I should help her stop cutting and trying to stay positive when she doesn't listen to me.

I mean, I know one thing that I did that was wrong, and that was not talking about her fear of being bipolar, but that's because I'm scared of finding that kind of stuff out and then having to deal with it.

But I thought since we were such great friends, we would last. But I guess because of all those things that I did or didn't do, we're not.

Because she won't even admit to me that she's mad at me.
