<human>: I just got offered a job that pays WAY more money, around 30-50% more.  The problem is, I don't think I really want the job.  What I'm doing now is probably more fun, I like the people I work with, and I'm not really craving change.

However, I'm finding it hard to turn down the money.  I'm living comfortably now, but this would definitely improve my quality of life in some ways.  (Better apartment, more vacations, etc.)

I'm thinking about bringing this offer to my boss and asking for a raise.  I don't think there's any way they would go as high, but even if I got a 10% raise, it would make me feel better about turning this down.  

I've heard of people doing this, but I've never tried it and I'm a bit nervous.  I'm worried that I'll seem like a dick, I guess.  Also, I've only been at my current job about a year, so I'm not exactly essential to the team (although I have been performing well).

Has anybody ever tried this before?  How did it go?  Will I end up looking like a fool when they find out I'm not really willing to leave for the other job?

If it matters, both jobs are software engineering positions, but in significantly different fields (hence the salary difference).

Can you summarize the given text in a few sentences?
<bot>: Has anyone tried to use a higher-paying job offer to negotiate a raise?  Did it go *okay*?
