This might kill our marriage?

We have only been married a little over two years. He is ten years older than me with a good career and he works long, hard hours and gets paid a lot. I, on the other hand, just graduated from college in 2006 with a degree in Mage Therapy and am slowly seeing it is not what I want to make a career of. To be honest I have no idea what I want to do. It seems like all the things I love to do are things you can't really make a career of (i.e. artsy-craftsy things) I'm what you might call a "floater". I've never been that "career girl". I've always dreamed of having a family and just either staying home or working part time. This is ruining my marriage. I have had a few jobs since we got married, but quit them (either because I hated the job or hated the people). My husband resents me. He says he feels taken advantage of. He said this is NOT what he "envisioned". I am not only frustrated with him, but also with myself. Part of me feels guilty, but then the other part of me thinks he should love me whether I choose to work or not. Sometimes I wish I had been "wired" differently and I had more of a career mind. Is it wrong that I am 29 and don't want to work at Subway? Much less feel the humiliation when other women my age see me working at Subway? I feel like a worthless loser. Everything that I feel gives me worth (playing guitar, singing at church...etc) is not something that earns money! I am open to any advise. I feel like he has a box that I just don't fit into.
