Irrational dual pairs are harder to make a real relationship to work I think- also ime too many IEIs become infatuated by the SLE and overly sexualize each other instead of respecting each other as well. I have seen too many IEIs get involved with SLEs only to then become bitter and jaded by them later on. I mean no relationship will work if one person is codependent and has too low of self-esteem and the other person is a narcissist.
Even though a real relationship with me and a SLE never fully materialized, they are still the type I fall in love with the most. For reasons that aren't about infatuation or sexual. A lot this pairing can have issues with lust ime... it's important to understand duality isn't really about lust. Although it's not not about it either probably.
I don't think a LIE would be good for me personally- other people have said that before, but I don't see it happening- it would be annoying because the supervision would seem like they could be my aggressors but both of us are Victims and it's like a thing where I want them to slap me in the face but instead they talk to me about the stock market or something.
