I know ibu and I feel about 14 for even thinking it, but it irritates me that my friend will flake out on plans with me, but is regularly tagged getting shitfaced with her 'other' bff, who, admittedly, does live nearer
I have had a rough old time lately for one reason and another. reached out to my friend and she talks the talk on WhatsApp, but blew me off when I wanted to meet up irl. I had a social thing coming up and she assured me she would 'deffo' be there and was 'really up for it' and would bring other people too (can't say what event was but I was kind of involved in organising and promoting it, and had a partial responsibility to ensure good turnout - event was free, in middle of day, in a venue amply served by public transport etc etc) .
I kind of just knew she wouldn't come, and sure enough, an hour before it started I got a text from her about how she was feeling so depressed and she couldn't move off the settee etc. she has various health conditions that tend to flare up when she doesn't want to do stuff - on other occasions she'll be the last woman standing at 3 am going 'right, where's still open??????' 
I just said fine and not to worry and obviously I understood as I have been struggling with depression myself lately. she replied saying how hard it all is and how we'll have to get together soon and I typed and deleted about three snippy replies before just leaving it and not bothering replying.
she was fine earlier in the week when she was tagged in a photo watching the england game round her other bff's house
and tbh I keep half expecting to see a similar photo pop up of them watching the final yesterday when she was supposedly prostrate with woe. she absolutely has form for this - but if anyone calls her on it she goes off on one with all the memes about fucking spoons and how no one understands 'hidden disabilities' and how damaging to ppl's mental health it is to call them out on being flaky etc, and has been known to have her husband ring people up all cross etc
I do love her and she is a good friend and has been for many years. I know I'm being kind of a bitch. I've been stewing about it all night and all day though. the event itself went well and was well attended and generally lovely. I was kind of looking forward to seeing my friend though, (even though I didn't believe for a minute that she'd bother coming).
I just wanted to put it all down somewhere to stop me sending her a grumpy WhatsApp suggesting she stops saying she'll 'definitely' come to things in future or whatever. I've restricted her on fb for now because I can't deal with her breathless gushy lovebombing comments on all my activity that she goes in for in the aftermath of incidents like this, I know I'll say something I'll regret.
