I had it in the primary for 5 days and it's been in the secondary for 3.
It's a shame that so much outdated, crappy info still persists out there, but racking to secondary is a terrible idea, unless you are adding fruit or are bulk aging a really big beer. I know that a lot of LHBS still put that info in their kits and instructions but it's not needed and is detrimental. That's a fairly big beer and by racking @ 5 days you removed the beer from most of the yeast and it likely stalled fermentation. Not using a starter likely didn't help either.
I would try to gently rouse the yeast, move it to the warmest room in the house, and check back in a week. If no change, you could try adding a packet of S05 to see if you can drop your FG some. A better plan on a beer like that would be to make a starter and leave the beer in primary for a full 2 weeks, verify you're at FG, then package. Good luck.
