To get frustrated by people taking several days to reply, or to stop replying at all

[Angelaanaconda1]

I don't hound them constantly with lengthy messages or anything like that.
There's one girl who I sent a very very short paragraph to with 2 questions in it, but she's stopped replying since Sunday.
What usually happens is that they reply to the first 2 messages out of politeness then stop. This is the first time I've messaged her since 2019, and have only done so as we're going to be staying in her area soon.

Another friend's Mum is going through treatment for stage 1 cancer I believe. She confided this in me a few months ago. We've exchanged a couple of messages of late, and in my last message to her 6 days ago I asked how her Mum was doing. No reply, but frequently online, posted pictures etc.

I guess these people just aren't interested in talking, I should accept it and never message them again. I'm sorry, but apart from certain circumstances it does not take 5 or 6 days to reply to a short message (well they haven't even replied).
I know people are 'busy', the whole world is busy. They may have forgotten to reply, but they've done this a couple of times.

Maybe I'm expecting too much, I shouldn't care what they think but it makes you feel like you're boring/annoying or something.
Does anyone else have this?

I am similar, I cannot keep up with messaging friends and go through flurries of catching up and then going silent for months on end. I’ve been assessed for autism under the NHS but told I don’t have it. However, thanks for MN I’ve been educating myself about ADHD in women and it strikes a huge chord. Hope to pay for a private assessment soon. I think this plays into not being able to keep up with keeping in touch consistently. For me, anyway.

It's rude. But on the other hand, it lets you off the hook. You can wait for them to text you now & decide whether you will respond or not.

I do sometimes take several days to respond, it's not intentional, and yes I am one of those who will start with "so sorry, I meant to respond tuesday!" My friends do the same to me, we are all busy, to my knowledge no one holds it against each other. By holding these expectations you may just be disappointing yourself by losing out on lovely friendships, I imagine that would feel lonely in time.
