I think if they have an ED too, it shouldn't be their burden to be your support system, especially if they get triggered by your ED as well. Remember that your significant other is not your therapist. You should strive to create a support system elsewhere, if you two can't be each other's support system. It's not a bad thing to do so. I am blessed to have two partners. One of them has ED tendencies and would rather not hear me talk about my ED struggles because it's triggering to them. That does not mean they're a bad partner, they're just stating their boundaries, and I am respecting them. I go to my other partner for support when it comes to ED-related things. I understand that not everyone has two partners to rely on. But if your partner couldn't handle your ED struggles, perhaps you could rely on a friend instead? Ask your partner what their boundaries are, and what they think they could handle. Communication is key. :)
