What to do for my aloe plant?

So i bought an aloe plant on 28th October 2009 after a week or so the leaves started to get yellow and thin on the tips so i decided to put it out on sunny days an water it once a week.Then the tips of the plant turned brown.I thought it might be a sunburn and i put it inside.The leaves started to get week so i decided to re-pot it since the original pot was small and keep it in.Now 2 months later it's a little bit taller because of the pot and i can't leave it in the house there is no space so i leave it out.But the temperature is getting to cold,there's no sun most of the days and rainy (7 Celsius --->44.6 F) and it hasn't grown bigger since i bought it.The leaves aren't very thick as they were i water it once a week or biweekly.What should i do?
