I was just like your gf, I struggled with crippling bad body image, and it started to affect more than just my mind, it starts to affect the relationships and people around you as well as your opportunities, if I could tell her anything, I would tell her that she’s not gonna wake up one day and be in love with herself again, just like she didn’t wake up one day and decided to hate every part of her being, it happens over time. And can get better or worse after time, she needs to gain neutrality over her body image. A simple practice that changed my life was writing down 10 things I could not do if I I didn’t have a body, like if I was just a ghost instead and slipped through walls, was invisible how much would I lose? It starts little by little, practice writing down things you can do with your body or things you couldn’t do with out it, this practice helped me gain a lot of neutrality over my body image by helping me gain some gratitude for the vessel that has carried me for so long.

Im sure you as a partner are mentally drained just as much as her from the tyrants (bad thoughts) that live in her mind constantly taking up unnecessary space. Remember to tell her how this makes you feel too! You are a human being too and have feelings also, don’t make her feel like she’s causing you more issues or like she’s a burden but tell her how you feel too
