I took the IA term to mean a one-way EA, meaning one party participates in it, views it and feels it as an EA, maybe even wants it to go PA, but the affair "partner" doesn't return the emotions/feelings.
I think in most cases person doing the IA ***knows*** that the affair partner isn't reciprocating. For example, I can have a torrid IA with Natalie Portman but I know she isn't reciprocating.
But what would you call it if I ***actually believed*** Natalie Portman was reciprocating in some fashion? Is it still just an IA? Or is it a DA/HA?
