I think it’s harsh to publicly describe your wife as neurotic for following basic etiquette
I've had plenty of people throughout my life express wanting to come over to my place and hang. There's definitely a social grace of how you'd phrase it, but it's not like it's some alien concept.
Coming from a very WASPy family, I am very much in the Guess culture -- for a long time I wouldn't dream of inviting myself over somewhere -- but I genuinely think taking some cues from Ask culture people makes a lot of things easier and more sociable.
