Boyfriends and EDs

the last one didn’t post, so I’m gonna write it again. I’m not really sure how to do this, so i’m gonna say trigger warning? i think. Anyways, my boyfriend and i have been together for 3 years on and off, not being separated for more than 7 months. He’s been through a lot, with the passing of his dad a couple years back, and his mom not really caring what he does (he was an oops). Recently I’ve noticed that he’s been losing weight, and hasn’t been eating much. We recently went on a 4 hour drive road trip and he didn’t eat anything on the drive. he did eat at our destination however. But, he was offered a Rice Krispy Treat this morning and denied it, as well as whenever i offer him food. I should also add that whenever I ask to go eat he pushes it off. I’m not sure if i’m overthinking, but i’m worried about him. Also, in his room he has empty chip bags and empty Nilla Wafer boxes. Idk if the stress he’s under or the fact i’m moving around 13 hours away is damaging him, or I’m just overthinking. Could he possibly have an ED? How can i help? Any tips would be appreciated.
