Did i ruin it?

So.. A week in I noticed the primary lid wasnt sealed shut on my Pinot Grigio. It's all cloudy and the temp is good.. So hope it's still ok..

It will be fine. No worries. It should be cloudy at this point - that is the yeast in it.

I kind of figured it would. Be just thought I would double check.. So what's the reasoning for sealing the lid?

There are two schools of thought on sealing the fermenter during primary fermentation. Personally, I do not seal it unless I am fermenting to dry in the primary, in which case I only seal it after the SG has dropped to the 1.015-1.025 range. It is during seconday fermentation, i.e. SG < 1.020 or so, that you should be careful to protect the wine from air. During primary fermentation, there is so much outgassing of CO2 that there is no danger of air getting to the wine.
