Is it wrong that I don't want to be there for my friend?
That sounds like a bad attitude to have. Why don't you want to be there for your friend?
I don't like her new boyfriend, he's really annoying and takes up all of her time.
I know that you probably feel left out of your friend's life now that she has a new boyfriend but it's important to make time for her. It's natural that she want's to spend time with her partner and you need to understand that and enjoy the time you can spend with her even if it's limited.
I'm done with her.
That seems like a really mean thing to do to her. You can find ways to spend more time with her.
