Job decision

Hi- I’ve worked as an educational administrator in a school district for the past 12 years. I want to go back to classroom teaching but I’m afraid I am making a mistake because my salary will decrease tremendously and I am currently an equal earner to my husband and we need both our salaries.  I’ve been thinking about this for a long time and the opportunity finally became available.

C- educational administrator in NJ school district
C-Gross Salary $170,000/year
C-take home salary with pension and other deductions $7890/month— 94,680/year
C-one of the teachers I oversee is retiring on June 30th
C-I am thinking of switching positions to a classroom teacher
C-highest a classroom teacher can make is 122,000 due to union contract
C-take home pay will be 68,000-70,000

T-I want to teach
T-I miss teaching
T-I want to use my creativity more
T-I hate managing adults
T- I am scared I’ll be making a mistake

I’m not sure where to go from here.
