Whose fault is it more and now what should I do?

I was in kind of a relationship with a girl with a girl from different city. She wasn't generally available for chat or call. She rarely initiated any chat from her own side and if I messaged her she replied after quite a long time.

Her reason was that she is very busy with house work and that she keeps her phone on silent mode generally.

She has a habit of sleeping early by 9:30 in the night and waking up by around 8 am then doing household work , taking care of her brother's family and his kids. Then sleep for three hours in the noon 2 pm to 5 pm. Then work again.

So , she doesn't have much spare time for me.

I always questioned about her feelings towards me because of her behaviour.

Recently she got really furious at me and texted really harsh thing about me , my family and also body shamed me and then blocked me.

Now , what should I do? I have texted her (SMS) sorry to her later.

Try to connect with her through her family or friends.
Let her connect. And if she feels sorry then continue with the relationship
Let her go. Even if she tries getting back it's better to part ways
