I'm going to end my 11 year old friendship with my best friend 2 weeks after her wedding
Why would you do that to your friend?
I don't like her second wedding.
If the two of you are really best friends, you should support each other through thick and thin. If you are worried about the person she married, that's one thing, but then she may need you more than ever. Rather than ending a friendship, be a real friend and talk to her.
You might think she needs me but you don't know what she really thinks.
I know your relationship with her may be very difficult. Like I was saying it's good to talk things out with your friend. Having an understanding can resolve your issues within this friendship and prevent it from ending.
