I've been a Police wife for almost 20 years.
It's hard, sporadic shift patterns, short notice shift changes (they only need to be given 4 hours notice), honeymoon postponed, DH did some undercover work so we went 4 months without seeing each other.
It does harden them too, DH is suspicious of everyone and everything. But he's also so generous, will help anyone and despite dealing with terror attacks and horrific crimes he is still a big softie.
Raising young kids is tough when their shifts and overtime is all over the place, but it gets easier.
DH is now promoted and runs a police station and is mostly on mon-fri 8am-4pm shifts now, with a sprinkle of lates and nights depending on events.
In my experience, you cant be needy to be a police officers wife. You have to be independent and able to run the home as a single parent with the bonus of a husband when they're not on duty or sleeping.
A lot is asked of our police, they're hated and vilified for always doing too much or not doing enough. Yet they're the ones who run towards danger so the rest of us can run away. It's a thankless job but one of the most important jobs out there.
Be very proud of your husband.
