Embarrassing family

I’ve been dating this guy all of a month and the first time he met my family (he wanted me to spend Christmas with his family and then go and meet mine)

My uncle asked “are you in love with my niece” and it had only been a couple weeks lol and today we both went to my aunts house to pick my son up and my aunt referred to him as my sons step dad.. I literally died of embarrassment. How would you feel
