Not an AIBU as such, more of a WWYD, but posting for traffic. Long story short, DH has a company, trader. He's done the job since teens but went SE not long after we met. He's great at what he does but not business minded so I helped him set up. Have done loads for him over the years in spare time and when on mat leave, I know the company inside out. Still do his bookkeeping and helped him set up new premises and interview new staff etc. In the last year or so the business has boomed and it's more than I can manage in my spare time now. He's hired a part time admin assistant now who's great but it's still not enough. He wants me to come on board full time. We've always discussed it but I never expected it to actually happen, or at least so soon. I have my own successful, reliable career and I earn well. I'm in two minds about leaving my career to go and work with him, for various reasons. He thinks it's a no brainer as I know the business inside out and if I didn't join him he would have to employ another person full time anyway. WWYD? Take the risk? Or stay in my career and take a back step from the business we grew together?
