OP it was exactly the same for me- my best friend of 15 years standing just dropped off the fucking map.
Id supported her through some horrific times, we lived together for 10 years and we were inseparable.
I had a baby at 29, unplanned, first of our group. Kept going out with my friends (just didn’t drink), was the same person, didn’t talk about the baby much.... she wasn’t at all supportive.
After DS was born she saw us twice? You know in the same coffee shops we’d been in before. Gossiping about the same people. I was making the same fucking jokes- just with a baby on my boob.
But it wasn’t about her seeing the baby for me- it was about her seeing me. Being my friend through all of it.
Then I had postnatal anxiety which made me really very unwell, and my relationship with my sons father was breaking down. I was man absolute wreck. She knew all of this and was nowhere to be seen.
I had to move 350 miles away to be back near family and she’s never visited- despite her sister living in the next town. I’ve schlepped back to London a few times to see her, and she got upset when I cancelled a visit because I had treatment for CIN2 and it really shook me (lone parent, no obvious person to have DS if anything happened to me... it just hyped up my anxiety for a while...)
When she told me it “was not okay to cancel like that” (a few weeks before, with a very honest explanation) I had to just accept we weren’t friends any more. Horribly sad, miss her every day, but what can I do? I had a baby, it changed me, it’s been a challenging time that made me, I guess, less fun- and she didn’t like it. I just wonder when she has kids, if she’ll look back and realise she was, frankly, a shit.
