I see the term 'emotional affair' bandied about on here a lot. I've never been clear on the definition. I get that it involves a romantic or emotional attachment to someone outside the relationship, but wondered does the other person have to reciprocate for it to be an emotional affair? Surely an affair involves two willing participants, not one forming an emotional attachment that may not be reciprocal or they may be unaware of.
Otherwise it seems like victim blaming someone who is the recipient of someone else's obsessive behaviour.
