It was nice of him to wish you happy holidays. Why not text him back and say thank you? Also, sometimes a text like that isn't some kind of breakup, instead it could be repecting that it's the holiday and you may have family obligations. It's not like this man is suddenly insisting on taking over your life or even pushing you for sex. He isn't even pushing for you to include him in your holiday either. Have you thought of organizing something you both can do for a date? Even going to see a movie with him?
