Brief background....friends for well over a decade via kids
Saw a lot of each other but drifted since covid but still in regular contact. Would meet for walks maybe every 3-6 months and have a good catchup.
I find my phone overwhelming so admittedly sometimes would not respond when she messaged, but she knows where I am and could always call or knock if I didn't respond to a message (though never did).
About a year ago I'm aware she split with her DH - don't know the details, she did tell me it had happened but again she messaged me, things were hectic, I had a lot going on personally and didn't respond beyond a general lets get together soon.
I will say here that she was very supportive when I divorced several years ago and always had a listening ear available. But at the time of her message I had a lot going on personally, an she didn't message me to get together soon.
Anyway, I lost a parent about 6 weeks ago, it was a rapidly escalating illness so although not entirely unexpected still hit us out of the blue, I'm still reeling.
Realised last week it was friend's birthday. So I messaged her on the day wishing her a very happy birthday and explaining that parent had passed away, still finding it very hard and asking if she'd like to meet up.
She hasn't replied, which I find very out of character. I feel hurt but I am not sure what my next move should be. How do you proceed if a friend has failed to acknowledge an even like this? AIBU to feel as upset as I do? I'm wondering if this is part of the grief rather than about her in particular.
