Re-enlist or get out?? HELP,

Normally I would tell someone in this situation do what’s best for THEIR family, etc. however my husband has put me in a very hard predicament. He has good days where he wants to do a full 30 year enlistment, other days he wants to just get out as soon as possible, which is common I know, but I usually just shrug it off cause he changes his mind almost everyday. Well last week he came home PISSED cause his 1sgt said he didn’t do anything and was useless, even though hes the only person in battalion that handles all fitness related things...anyways he comes home pissed says he’s getting out and he’s going to be a truck driver cause a friend of a Friend said he makes 70k+ a year... there was no discussion EVER and when I tell him I don’t think truck driving is the best option for our family cause 1) we would go into debt buying a truck cab cause those things aren’t cheap buy any means 2) he would be gone way more than he is now(he’s in a nondeployable unit and is home everyday by 4) 3) there is no guarantee of having any health insurance for our family and 4) there’s no guarantee he would get a steady pay check. He said I was then being selfish not letting him do what he wants 🙄😒 he’s only looking at a dollar amount and not everything else. He wants to get a job making 70k+ with out a single college degree or trade certificate, which is damn near impossible. I think he needs to stay in for atleast one more enlistment so that 1) we have a guaranteed roof over our head till he figures out what he wants to do 2) we will have great health insurance and 3) he can work towards some sort of degree or certification he can use in the civilian world. He has done SO many amazing things and made e5 in three years, in all ways he’s an outstanding service member. He just HATES his command, which drives me crazy cause the people he works with now aren’t gonna be the people he works with in a year from now. I need advice and guidance in what to do...
