Where in Ga are you? I have 6 kids. My wife and I each own a business. Those hours are not sustainable to stay married and engage with your future kids. Linemen make good money and can turn into a great municipal job. Keep you side hustle going if possible. Fire department will be fine without out you. Volunteer somewhere if you love it that much. I was active duty coast guard for 9 years. Been a reservist for 8. Make wife / family priority.
