I'm going to tell my friend she's still single due to having 5 babies by different fathers
I'm shocked. Why do you need to confront her though?
From what I know, she always want to be with different kind of men. She's not good at choosing partners for herself.
I understand that you are concerned that your friend has been with alot of different men and had kids with all of them, but insulting her for it is just degrading to her. Don't say anything to your friend, and instead just be there for her to support her no matter the choices she has made.
Whatever. I already hate her for not giving me her left over food.
I feel like she may need that food for later and saving it for her or her kids, so I do not think she's being rude about it. As I have said, you need to support her moving forward but it seems like you hate her more than you want to admit, and hating someone doesn't make her a friend, and you can either work on removing that hate or just mind your own business and move on.
