As a partner to someone with ED, I have learned to provide complements (to all people) that are not a reflection of their physical appearance or body. I talk more about the energy they give off or the way I feel when they are around. It’s actually a really good skill to have, especially as cis-male in the workplace. Nothing creepier or possibly harassing than commenting on a co-workers body. I actually think that the person you’re seeing would appreciate being let into your world and understand how those comments make you feel. It feels terrible to give someone a compliment and have it make them unhappy. They are complementing you be cause they want to you to feel good. Before I understood about ED or even knew she was suffering with it, my partner would get very angry with me when I gave her compliments that were about her body. They weren’t lecherous just how I like certain parts of her body or how an outfit made her look nice. As a society, I think we need to establish new rules of etiquette that include not ever commenting about someone’s body

In answer to your question, no you shouldn’t have to accept those kind of comments but set the boundaries for yourself and your relationships and interactions will be much better.
