Well that just sucks.
I have a career pickel too. I interviewed for a job, got it. Then told my current bosses I was leaving. They gave a weak counter offer at best. HOWEVER, I do have amazing flexibility here and I am very comfortable. And my new big boss has some ugly things being said about new boss that is scary for me to think about working for them......long story short, I've decided to stay where I am.
The new boss finally calls and wants to give me the official offer. The new boss says "Do you accept?" I had to say yes because my current bosses can't give me the raise without seeing the new offer. So now, I have to call and say "No thank you." Basically, I'm not just burning a bridge, I'm about to torch it.

The other sad thing I had to consider is if I am going to suffer the big D, I need to be someplace where I can have a break down, and that would be here.

Not looking forward to this at all.
