"It's just the...RULES OF FEMINISM!"
You know the unspoken rule of friendship, don't date someone your friend has already dated. Right?
I had a few friends who were part of a different, larger friend group in high school.
For some reason, they all seemed to be dating each other throughout the four years.
Janet would date Ian, they'd break up, Ian would date Maggie who was best friends with Janet, Janet would date Kyle, Kyle would eventually date Maggie, Ian and Janet would get back together, etc etc etc
There were like, 6 or 7 guys and girls and they'd just trade partners but still sort of remain friends even though it was probably super awkward?!
It's easy to date in your friend-group but does it cause more problems if the romance ends?
