Passive dread is more or less just being attractive enough for other women to notice.

You're walking with your gf and a random girl sends an IoI.

You don't even have to notice it your gf will.

or

You get a message from some girl in your past hoping to reconnect and your wife see's it.

or

A women who struggles to find a husband tells your wife to be thankful she found such a great husband.

Just a small reminder that she locked down a man who is desired by other women.

Passive dread is a normal thing in relationships but usually it's the woman who is doing it to the man.

Does the average man inspire soft/passive dread in his gf/wife?

The average man ...the 5' 9'' ,dad bod, graphic tee/cargo pants wearing , minimally groomed , beer gut, sports watching man.
