Fiance and I started a business in Oct 08. He'd been Djing for years for friends for free minus the fancy equipment. I suggested that we go into business. He's great at working a crowd and LOVES people. We work as a team. He currently handles our website as my internet is too slow to work on it. I handle the Myspace page and fliers, and business cards design. He takes care of making sure the taxes and what not are paid off as the business license is in his name, we felt it was easier this way for tax purposes. It's my vehicle that we use as our "company car", though he bought it for me as a surprise ( I really do have a great fiance). When we are at a job I'm the one in charge of all the music while he goes out and has a good time with the crowd (this is what makes us different from our competition). He'll dance with the single ladies, teach dances, do the group dances with them, etc. And I have to be honest I don't feel like I get the credit that I should because people do feel a little uncomfortable approching me at times because I do look like a child even though I'm 21. He tries to make sure to tell me that I do a good job and stuff, but it's the things he says when he's talking about it to each other and yea sometimes other people. After he got the taxes done he didn't ask my opinion he said "I'm thinking about letting our business license run out" me: "What?" and he explained that the tax woman told him she'd recommend he let the license run out (WTH? what sort of tax lady is she anyway?). And proceeded with "I'm not sure yet. I'll think about it". And sometimes he does call it "mine" (his) instead of ours. I've asked him many times if he really feels like it's "ours" and he assures me he does. But yet I still here this "mine" and "i" and of course from the clients he gets the most praise even though I'm there through all their planning and the event too. They'll say "we done a great job" at the event but when it comes to sending the letter of recommendation it's "JB done a great job, I'd recommend HIM to anyone".  It's sorta like I was there too. I've seriously considered quitting but he begs me to stay on everytime I bring it up. How can I make things change? Is it "his" or is it "ours"?
