hey, saw in another thread that your FI is a police officer. my husband is as well.
the schedule is trying and difficult, but it does get better! after 5.5 years on the job, my husband finally had enough seniority that he got his pick of shifts. he still had to work holidays and weekends, but no more overnights except on order ins. shortly after that, he went into a specialized position which now has him on a 5-2 schedule (verus 4-2) so he the holidays off and every sunday.
you do get used to doing stuff alone alot, but its not so bad.
