You’ve had five marriages dissolve
Grammatically, should this sentence be “You’ve had five marriages dissolved?” Just like the structure “I got my hair done”
Well, here’s a flash for you. We’re all desperate to be relevant.
In this sentence, what’s the meaning of “to be relevant”?
Recognize that this is not the perfect tense had dissolved. This is the perfect tense of have (have had) implying ownership or experience
She’s had her life take some unexpected turns lately.
This structure is also akin to the passive tense. By making the marriage the subject, it implies no fault — no one actively dissolved the marriage or had someone else do it. It just happened on its own. Another example:
You’ve had your house increase in value lately, haven’t you?
implies the increase is something that happened “on its own”. Compare this with
You’ve had your house repainted lately, haven’t you?
which implies that I took action to have someone else repaint the house.
To be relevant is, I think, a somewhat modern idiomatic expression that means to be of importance or of significance to some group.
As our children become adults we have to acknowledge that we inevitably are less relevant to their lives.
