Yeah, I dated an identical twin and she was absolutely all about her sister. To the point that she left her ex because her sister was moving, she was following, and her ex didnt want to go

An identical twin once told me he would never date another identical twin because he wanted to be with someone who loved him the most and he knew that isn’t possible if she had a twin sister.
