Hi Suzi,
I've recently just posted a brief overview of the situation..
I don't think she was eating properly, but I honestly didn't pick up on the signs! When she said she didn't want dinner, but she would cook for me and I would just say "don't worry I'll eat at home before I come to yours" I was in the dark about it then, and just assumed maybe she had a late lunch or something, but had I known she was suffering I would of been much more supportive.
I noticed little things like her fridge always being empty, but as stated, I didn't take much notice because I didn't understand she was going through something until she told me a week later after she said she didn't want to see me
I am not sure at all about that, I think 4-5 weeks later to just ask her about it won't feel right... But I did my 'weekly check in' on Wednesday and she told me she is doing a bit better and that one of her friends has moved in, which is fantastic and means she has someone there for her that is looking after her, and I genuinely felt a bit of pressure relieved inside of me knowing she could count on someone.
