"$8000" is an odd statement. I don't want to make assumptions without more detail.
However, $7000 is not only your personal maximum, it is your family maximum. You and your spouse may have separate HSAs, if one of you is covered by a family HDHP and you have no other disqualifying coverage, but your aggregate contribution limit is $7000, plus $1000 for each spouse age 55 or older.
