Super newbie looking for a good start!

Hi guys!

Well as my thread title states, I'm very very new to the orchid scene. I got this orchid for my wife, and it's been about 2 months since then, and it's starting to look rough..

Here's how we've been caring for it:
- Water every 25 days
- Keep it near a window that has plenty of sunshine coming through it
- Our inside temperature will fluctuate 2-7 degrees, I'm located in Dallas and it's 42 one day and then high 70's the next..

Other than that I don't have any experience with these plants and neither does my wife.
Where should I start out reading and educating myself, or what are your opinions on how to quickly get this orchid back on track?

Thanks,
Marshall
