Siblings dating ex girlfriends
Oddly enough, this kind of thing happens more often than we think it does.
No Southerner wants to contribute to inbreeding jokes more than they absolutely have to. One person wrote about his dad dating his aunt before marrying his mom.
He claimed his dad was dating his mom's sister because she was the "second best" choice before ending up with his mother.
Another person wrote about a similar scenario where his dad was dating his aunt back in the day.
Eventually, they broke up, and his mother ended up dating and marrying him.
Social conventions of dating stipulate that friends and family members of your ex are off limits.
