I haven't heard from my friend for about 8 weeks. This is very unusual - normally we're in contact most days if not every day. She has depression and this year has been very difficult for her, so sometimes she didn't respond to messages for a few days. Which is fine, I understand that she may not be able to reply or do anything much and I wanted to support her with that. I've really gone out of my way to help her in general, even when it's meant some sort of sacrifice on my part (I haven't told her about this).
Up until yesterday I had assumed she was just really struggling and I've sent her a "I'm thinking about you"/"here for you"/things that made me think of her message every so often, so that she knows I care and I'm here just whenever she's ready. She hasn't opened any of them and has been sporadically active on social media.
Yesterday a mutual friend posted a photo showing that my friend was out for the day with a few other mutual friends. She is of course allowed to do what she wants with whoever she wants, but aibu to feel a little bit hurt that she hasn't contacted me in eight weeks but can go out with her other friends? I honestly can't think of anything I could have done to upset her, and as I've said I've done my best to be there for her and she has confided in me a lot, so I thought we were close enough to be able to be honest with each other about stuff like this. Maybe I shouldn't take it personally but I do really care about her and in a way I feel used that I put so much effort in for her and yet it's as though I haven't existed for two months.
