How long is too long in the primary?

I have some cider that has been the in primary for almost 2 weeks and is still going strong (after about a 3 day delay start). However, I am about to go out of town from Dec. 12-Jan. 16. I was anticapating moving it into the secondary in a couple of days before I left, but clearly it is not ready (the OG was 1055 and has only dropped to 1046).

So, my question is, will it be bad if it stays in the primary that long (about 6 weeks overall)?

Also, if I go ahead and rack into a secodary whould that harm anything?

I would leave it, it will be fine. Just hard cider? or Apfelwein?

Hard Cider. I used 5 gallons of fresh cider and Wyeast's Belgium Ale Yeast.

Any other concerns with leaving it in the primary that long?

No concerns. I have left cider in the primary for over 2 months with no off flavor development.
