Cuz it's been ages and 2 fights and I still don't feel like I'm being acknowledged and it still hurts

I have not been in this situation before but I can imagine it is upsetting.

If something is a trigger it is not ridiculous. It means that you are feeling similar to what you have felt in the past. This situation triggers those feelings. What I had to do for myself, and this not an immediate fix, was go back to my childhood and learn where all the feelings originated and then heal them.

For me, a very big trigger was being ignored/not acknowledged and it sounds like that is a big trigger for you too. You definitely deserve to be heard but it sounds like your significant other may also have issues that are preventing this. Have you thought of doing couples therapy?

Sometimes we use food to express what we feel ashamed of feeling. And so it makes sense to me that this is a trigger. Don't be so hard on yourself or judge yourself. The more you judge yourself, the more this can become a trigger. Can you talk to your Significant Other about your feelings calmly?

I think you need to ask yourself "why is this a trigger for me?". And in what way were you triggered? Did you binge and purge? Did you calorie restrict? You have to deal with the feelings that your "trigger" causes you because unfortunately, we can't necessarily avoid things that "trigger" us forever. You have to figure out what about your SI tagging her ex bothers you so much. Is it fear that there is still a connection there between the 2 of them? That can a lot of times bring up feelings and fears of abandonment and mistrust that you may have learned to carry around with you from an earlier experience.
Next time, instead of letting yourself get triggered, write down/journal your thoughts and then try and ascertain what is really at the root of your feelings. It really does help.

Thank you for your response. Next time around, I definitely plan to be mindful of triggers and to try to figure them out before I allow these reactions.

Unfortunately, my partner is far too frustrated of my ED to make any acknowledgements to this and I can't help but feel disrespected. Idk about anyone else here but if it were me, I'd know enough that nothing else matters but for the health of my loved one and if this brings out negative emotions and I know it, i wouldn't think twice about taking it away. She doesn't have ED. But not long ago, I also had to make "sacrifices"

....just saying, I never flinched in taking action towards what I knew was right.

I gave her my account links to this so that she could know what's on my mind. lol I don't even know that she remembers that it's here.

...,idk. But it's lonely. And it angers me. And it breaks me. ...and it fucking sucks.

PS- you were right. It was from the past. It's a cumulation of all kinds of long as traumatic stories but...I get it now. I've cut them
Off so there's no better healing from those assholes but I have to. And it's slow and it's progressing but I'm afraid it's too slow because the one person whom I have to depend on is waaay to frustrated to see this. And I'm fucking pissed off. And I'm fucking hurt. And I should be more fucking important than her frustration towards this fucking disease and I'm not. And I'm tired. And I don't think she thinks I deserve to have rest because it's me that carries this. And it fucking sucks. Like:..lol this fucking sucks
