Husband question

So my husband shared something with me today. Yesterday he was with his family and uncles and aunt. I've been married to this man 10 month. He said my uncle asked about you, and Said is ur woman still skinny or did she Gain weight, he said I laughed and his mom jumped and and said oh she got skinner. Then he went on and said that his mom shared this story with them about when I took her to an appointment and how her friend ask who I was and she told her that I'm married to her son. And told them her friend said damn she's skinny, how would she have babies. I just felt so bad, like he was laughing about it. I didnt find it to be funny. This is not the first time his mom made comments like that. She even said to me to go check myself.. why would he share it with me? And his intention
