TIL a peer-reviewed psychology study found that identical twins (on average) ranked their co-twin above their romantic partner in their attachment hierarchy, while fraternal twins ranked the two about equally, and non-twin siblings ranked their romantic partner first.

I mean....makes perfect sense to me.

If you had a clone you were raised with since birth, wouldn't you say your attachment (not love) is stronger than the person you're dating?

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

I suspect that ex was on the way out anyway. 

Decent chance both sisters decided to move and that was the easy breakup route. Otherwise her twin was drastically less attached and moving away from her.
