There’s so much I could say tbh but we’d be here all night. Ultimately, my mum and I were best friends growing up and until I was about 28. I’m 33 now and over the last 5 years we’ve grown apart which I feel really sad about. I guess I’ve come to the realisation that I just haven’t got a lot in common with her anymore really but at least she used to care, nowadays I feel like that’s not the case.
We tend to facetime once a week, but I’d say the last 5-6 weeks it’s been me that’s calling her every time . It’s usually on a Saturday and I will text her on a Friday saying I’ll call her tomorrow, what time is she free.
When we do talk she seems ‘meh’ from the minute she picks up. All she ever says is ‘oh well, I haven’t really got a lot to say due to this lockdown’
and I get it, none of us do really, but then she ALWAYS, every single time I speak to her, lets slip that she’s spoken to my sibling throughout the week 
we used to text each other throughout the week too up until a few years ago, now we rarely do.
Today I was going to send the usual message and then I thought, no, I’m not going to message, I’ll see if she messages me (she hasn’t) or calls me tomorrow or whether I just won’t hear from her for another week?
I just feel sad, all of my friends are so close to their mums and I used to be with mine but she just seems to have little interest in me anymore 
A few years ago I did what I did tonight and I didn’t speak to her in 3 weeks!! I remember telling my work colleagues at the time and they were all like ‘wtf?! That’s so weird, does she not wonder whether you’re still alive?!’ So I rung her and said I was upset that we hadn’t spoken in 3 weeks (I had tried to ring but got no response!) and she apologised and we’ve never gone that long without speaking since.
If you haven’t fallen out with your mum, how often do you speak to each other? Who initiates contact? Is it equal or one sided?
