Getting hurt feelings

My cousin that I rarely get to see ( I’m 69, she is 73) told me at a recent get together that she wanted me to loose weight. The last time I saw her about 6-7 years ago, she told me the same thing. It hurt my feelings and pissed me off. I would NEVER say that to anyone. Am I wrong to feel this way? There are things I could have said to her, but I didn’t think it was a good idea. I love her and don’t want to lose her.
