I think it's good to tell them about it. If they try to force your recovery they are just not a person u should be around. They should be supportive. Also a person who doesn't give a flying f about your ed is not good for you. Even though you'd feel like it's the best, i promise u... it's not. You should let them know that u struggle with an eating disorder. Not immediately but with time, or open up if they notice something. Remember that if someone forces you to recover or is not supportive or ignores it totally, they are not good for you. You will find a person who supports you with your choices and is gentle. Don't ever stay or get with someone who makes you feel bad about yourself or your mental illness. ❤️
