Your boyfriend has a right to file a lawsuit against you. However, if the money was given as a gift, he doesn't have a right to repayment and the court will dismiss the lawsuit.
In order to get the money back, your boyfriend will need to prove that you entered into a contract. This means that he'll have to prove that both of you intended to enter into a contract and that you gave him something in exchange for the money. Based on what you told me, it doesn't look like your boyfriend can prove any of these things.
