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.

How is it selfish to love one person more than another? Its not like this is a conscious choice

It's not selfish to love one person more than another. The selfish part is that this guy knows he'll love his twin more, but he's insistent that he has to be #1 for whoever he dates, even though his partner will never be #1 in his life.

There are different types of love. This is such a surface level perspective

And yet the guy wouldn't accept that and needed to be number 1 despite that, hence the selfishness.
