He sounds completely burned out and he's not happy with his career. I can perfectly understand that. I just think he needs to step back and thing logically, not desperately.
My husband works full-time and is going to college. He's doing the fast track program. I'm not sure where you are and where your husband is interested in going to college. But, there are lots of college programs out there for people who are going back to college. My husband has class every Tuesday night from 6:00 to 10:00. It's very hectic for him and he stays extremely busy between work and college. But, he graduates in December. So we can see the light at the end of the tunnel. LIke your husband, he was completely burned out. He owned his own business and sold it to work for somebody else while he goes to college.
In the program my husband is in, the classes last for one month. So instead of a class lasting 15 weeks, it's crammed into 4 weeks. That's why his classes last so long on Tuesday nights. Some months his class is on a Saturday all day. He's going into the ministry. I had some friends when I was teaching who did this in education. So have him check more into programs that are for people who work full-time.
Also, is there anything you can do from home to help? What about babysitting? I can understand why it wouldn't be worth it to work outside the home with paying for daycare.
So hang in there. We did a lot of praying before we made the jump. We did a lot of praying before we sold dh's business. It was a major move but so glad we did it. Even though my husband is not happy with work, he can deal with it because he knows it's temporary. He's working towards something and that really makes him happy again.
