your boyfriend is purposely throwing low-blows to hurt you. this is not respectful of your wellbeing and is an immature and cruel way of fighting with you. if you wish to continue your relationship with him, perhaps he should read up a bit on ED or visit some websites aimed towards friends and family living with an eating disordered loved one. i hope this is just and example of his ignorance rather than a complete disregard of you as his partner. one thing that helped me get through to a partner like this was to write him a letter. I never got to get my point across during an argument because he was so mad that he wouldn't listen to my side at all. being forced to read something is one way of making sure they hear you. good luck to you and take care.
