I'm annoyed with a friend because of the guy she's seeing
Why does this make you feel annoyed?
If they are in my friend circle then I would avoid them.
It can be hard to be annoyed with a friend and a friends new boyfriend. But, talk things out with her before this situation turns into a bigger issue.
Fuck that, I can just not be friends with them. Who do you think you are telling me what to do?
If it's continuing to be a struggle to maintain the friendship, try to sit down with both of them and have an honest conversation
