I would answer for both you and your spouse that
I was covered by a Family plan every month of the year
for the first two months, you were both covered by your Family HDHP. I assume she was not covered by another plan that was not an HDHP
for the last 10 months, it seems your family was covered by your spouse's HDHP.
the rule is that if either spouse had family coverage both spouses are treated as having family coverage.
