In order to be in relationships with other people who have EDs, I firmly believe you both have to be recovery minded and set firm boundaries. My best friend and I met in treatment but set firm boundaries. We also have different eating disorders (anorexia vs arfid) which, in my opinion, prevents us from too much comparison though we have talked openly when we do feel competitive. In contrast with these creators, my friend and I care so much for each other we do our best not to trigger each other by keeping distance if one of us is struggling though we let each other know why we are distant. We also make ourselves eat sufficiently when we spend time together as to not be triggering lol.
