Question

So I want to ask for a raise at work.....well I kind of already did. But how do you go about the most professional way? I could say I will quit if I don't get a raise, but in reality, I love my job, and really can't afford to quit seeing as it is pretty much the only health club in town. So if I say that, and they so, sorry see ya later-then I am gone. But if they think that I love my job, and will never leave, then they will never give me a raise, because I won't do anything drastic about it anyway. So what do I do? Do I just present my case and hope for the best, or do I become more aggressive hoping I still have a job at the end of the day. (ps. I really love my job, and don't want to leave.) AHHHH I am so torn. What would you do???
