I think the fundamental truth here is that any relationship requires conscious effort from both parties. One person alone can’t carry that weight. If your friend wants to salvage this relationship then I think they need to convince their partner to pursue individual therapy, and also they need to talk to a couples counselor together. Without professional help I think it’s going to be very difficult to shift the dynamic here. That being said, life is short, and you can waste years hoping that someone will change. Sometimes you have to make the hard choice to move on.
