It's easy to be sensitive. I am too, sometimes. Medium is tough, because people comment. I wrote without feedback for decades, so getting reader feedback was a bit of a shock. I wrote about it here: https://medium.com/life-tips/how-dare-you-say-that-7e6209862c9a

I think the 'let's eat healthy together' thing though is really nice. My hubby has a health condition and we're going on a diet together to see if we can fix it. It's not him on one thing and me on another. It's doing it together for support. It's great that he wants to take you along for his ride. Go with the flow! Unless you hate it, and then whatever suits you. But I'm all up for trying these things.
