Hold out for duality unless someone comes along that you fall in love with and with whom you want to spend the rest of your life.

I will wait for an EIE. I'll pick them out of crowds, assess them, size them up, interact with them, and engage them if I think they're excellent enough for me (I'm a catch, face it).

However, I will also happily accept a fun, outgoing IEI who likes to talk about intellectual stuff and who is really into me. I don't want to feel like SLEs are always tugging at their strings.

I'd also not mind a smart, fun ESE. The Si/Se thing isn't much of a hurdle, and the opposing hidden agendas can be shirked off after minor rows.
