He offered to gives a discount to peopleemployees from our company. He offered to give a discount to employees from our company.

Gives = present tense, but you need to write it in the past tense because it already happened.

He gives a discount to people from our company. He gives a discount to people from our company.

So / Therefore, about a year ago, me and my girlfriend and I decided to use this opportunity to spend a couple months in Spain during the winter. So / Therefore, about a year ago, my girlfriend and I decided to use this opportunity to spend a couple months in Spain during the winter.

So is ok for casual writing but therefore/consequently/subsequently etc are better. me = direct object Here it is the subject so you have to use "I"

So, about a year ago, me and my girlfriend decided to use this opportunity to spend couple months in Spain during the winter. So, about a year ago, me and my girlfriend decided to use this opportunity to spend couple months in Spain during the winter.

Technically this should be phrased as: So, about a year ago, my girlfriend and I decided to use this opportunity to spend couple months in Spain during the winter. I wouldn't worry about this one very much. Even native English speakers mix up me and I in situations like this.

So, about a year ago, me and my girlfriend and I decided to use this opportunity to spend a couple of months in Spain during ( the ) winter. So, about a year ago, my girlfriend and I decided to use this opportunity to spend a couple of months in Spain during ( the ) winter.

"my girlfriend and I" is grammatically correct, although in informal speech you will definitely hear "me and my girlfriend" - technically this is incorrect, but it's such a common error that it wouldn't sound strange at all (I would suggest you learn the "correct" version first before allowing yourself to make these kinds of "acceptable errors")! I would also suggest that "during the winter" sounds slightly more natural in this situation, but the difference isn't very significant.

"A weather" is never used, it is always "the weather" or just "weather".

two independent clauses linked by a coordinating conjunction, it needs a comma.

This only applies if you are in the UK or learning British English... be careful with "licence" (noun, as in "driving licence") and "license" (verb, as in "to license", which means to give someone official permission to do something. In the US, I believe "license" works as both a noun and a verb :) I would also repalce "it" with "one" here.
