Honey, I'm right there with you
My step-mom said to me, after one of my cousins got married in 2000, "You'll be the next one in the family to get married". This would be before another cousin, who's three years older than I am, and my step-sisters. As of this point, I'm still unmarried (no prospect in sight), as is my cousin, and ONE of my three step-sisters.
I also have a majority of my friends from college and high school either already married or engaged to be married within the next year!
It's crazy!
