I'm year of the horse (september,26,1990) and my bf is year of the sheep (feb.26,1955)

My question is, he's putting some buisness on there country. its a work shop buisness about cars,(how to repaire your car) and he spend a big money for that buisness, even the space rental was so expencive. me I'm going to work there on his country as a care giver, do you think he made a right decission for that business? And I want to help him too and ofcourse I give my whole support for him, but for me I don't know if he can get back more than times 2 the money he invest for his own business, and as I've read on his zodiac sign there something possible happened about his buisness plan and I know its only a guide, please help me and I need some advice, thanks
