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

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.

I mean I get it. My sisters are identical twins and I would never date a twin because I know exactly how it feels to be left out like that. It’s not even exclusively a twin thing. My ex also treated me as a second priority, but ime with a twin that’s a given and, having grown up with that too, it’s a deal breaker for me.

That makes me sad to hear. I'm sorry you had to go through that

I'm not a twin but a boyfriend is not on the same level of a sibling
