I was given an amount of money (less than 2,000$ CAD) as a gift from someone with her confirmation (by message and on paper). At first, I told her that I would accept the gift, but in the future, if possible, I will return it as my will because I do not want to owe anyone any amount of money (with no confirmation of the exact date/time to return it). Now the relationship has gone badly, and she asked me for the money back and told me that she would bring me to court for this.
Can she legally do this, and am I obliged to pay it back?
