It's impossible to have a mutually loving relationship with a narcissist because they only see themselves. they don't see us. So it is experienced as an unrequited love, we love but we aren't loved back. Maybe that's partly what is being replayed in therapy? Not because the T is a narcissist (though I think quite a few are) but it's the pain that we're seeking on some level to replay... maybe to process the original pain??

It's great that he has acknowledged your feelings. that's a good sign already.
