Invites for Thanksgiving

The other day I learned thru my son that if I invite a friend for Thanksgiving dinner, whom I know has the desire to have more than just a friend relationship with me, would not be a good idea. I don't have the same desire & to invite someone to a family gathering knowing that, it could be 'leading' him on. I just want him to know that he has a place to go, not to feel left out if that may be a possible feeling for him to have. He's not from the states so didn't grow up celebrating Thanksgiving but he is in this country now. What is the most loving thing to do?
