I had an experience where I nearly died, thought I might still die, text my "best friend/sister I never had/godmothers to each others children/chief bridesmaids/baby shower hoster etc" from the hospital to let her know the situation and she left me on read for nearly a month. We'd usually see each other at least once a week.
Didn't make any attempt to contact my DH or family for an update. Her sister in law heard from their mother in law (who she'd told) and her and a niece both came to my house to visit long before she ever acknowledged it. The only thing worse than thinking my number was up, was thinking that my best friend couldn't be arsed to make any contact with me and had read and thought, "can't really be arsed to reply to that." I was pretty heartbroken and it didn't help me to recover.
Anyway, she's become a terrible texter. Takes a month/six weeks to get back and I've gone through what I've assumed was the slow fade multiple times and given up only for her to return from the dead with a grovelling and increasingly far fetched apology...I mean dogs licking phones and deleting messages, broken phones, eye infections where she couldn't see, husband/kids/postman accidentally deleting messages right before she pressed send, random cloud/wifi/whatsapp not working and a series of hysterical reasons that mean it's been absolutely impossible for her to text. If I am to believe her it's been several years since she has sat down or slept. Our conversations now are pretty much a monologue of all the million reasons she hasn't been in touch, meaning when we are in touch the conversation is one sided and boring now.
When we see each other after an age of not responding (she usually gatecrashes another meet up with mutual friends, or mine or her relatives that I arranged because she's "desperate to see me") she expects that I should just be able to be normal with her. When I've been really fucking hurt, multiple times. I've also been worried sick about her, thinking she's cracking up or in some sort of problem, reached out and found out she's been "fine, just didn't get round to it".
I've given up messaging her, then will get a text, "haven't heard from you for a while...I love and miss you. Are you offended with me?" and I'll text back "I tried contacting you three times a month ago and you never replied." then get something as far fetched as "yeah, we've all had small pox and next doors two week old deleted all the contacts so we had to wait for the tornado to pass to get to the Highlands to visit the only O2 shop which deals with this iphone as it's a special edition".
I don't know wtf it's about and I've tried other options, given up thinking she wants out, made as much effort as I can but there comes a point where it's just mind boggling and ultimately very hurtful as in the situation I opened with.
I find it very rude.
I'm ND and have executive function problems that are severe. When sending a long response is overwhelming, I at least text to say, "Meg, I'm so sorry that I've not text back properly last night but please know I am thinking of you and will be in touch by the end of the week when I can give you the sort of attention it deserves. Also please let me know if a cuppa would be better for you and you need to chat in person as you can come over this weekend anytime x"
Ignoring a person for an extended period repeatedly, whether people consciously realise they are doing it or not, is sending a clear message that they don't matter to you.
It's becoming more common. Other excuses I get a lot are very like what Mel Robbins says and along the lines of "I LOVE you and think about you all the time, I'm just a shit texter/peri menopausal/menopausal/post menopausal/tired/stressed/forgetful/ditzy/loved up/have a puppy/" etc
Then in another breath, complaining that they have no friends anymore and ABSOLUTELY NO TIME but telling me they binge watched 24 episodes of something on Netflix in one weekend or spent a whole day buying stuff on Prime etc.
It's like people have forgotten that friendship takes effort. People just seem to be disposable now. I hate how much the ability to connect has been eroded.
