Just ended a very long term friendship

Not sure this is the right forum. But hey, I'm new, forgive me if I'm wrong

So basically I have been friends with this girl for over ten years. We talked a lot and shared loads of moments. For the past year I have been struggling with unemployment and lots of other things come with it. But she was just..too rich to get. All her replies were like, so? Get a job then? My uncle has got a job very easily when he graduated. I don't blame her but it still sucks when I can't get any emotional support from someone who matters to me so much.

I learnt to avoid heavy topics and just talk casual things like foods and games with her. But no she's not happy with how I reacted to her favourite "local culinary", which, explained by her, is boiling foods in water without any seasonings. I admit my response might be a bit offensive. I genuinely thought and still think such a dish should be simply called food crime. But I got her point. She's defensive about her culture. Even though I actually googled the dish she mentioned and obviously those dishes actually use seasonings.

She stopped messaging me since then. I know it was my bad speaking ill of her favourite dishes like that. But I just don't want apologise. Look, I'm no jerk, if it's a stranger I wouldn't have said those things, and wouldn't mind apologising if I accidentally offended them. But she's the one who has been dismissive towards all my stresses irl. She's the one who I've been sharing my life with for over ten years. If she's behaving like someone who doesn't care about my pain, why should I tiptoe around her feelings? I've swallowed so much discomfort from her out of touch replies, and she can't take my one negativity about her food choice? After TEN YEARS?

If this friendship is gone it's gone. I'm not gonna save it. I miss having a good friend that listens and knows me. Unfortunately the maintenance of this friendship is costing more than the comfort it can bring to me.

It's just so sad that I have to end this relationship over some stupid foods. I'll miss her.. probably. Forgive my grammar. I'm still processing this whole thing. She was a really important friend
