Xavier, 27, found out through mutual friends that his ex-girlfriend was seeing a guy who looked like him. “He looks exactly like me but just shorter ― I’m around 6’1,” Xavier told HuffPost. “He has the same haircut as me at the time, style of tattoos, music interest, hobbies interest, you name it. “It’s just like how frat bros always date the same type of girls over and over,” he said. “I’d also say geography, finances, and status plays a huge role in influencing our decisions on who we date.”There’s a reason we date people who look like our exes, according to evolutionary psychology.
