(18M) (18F) how do we continue forward?

Sorry for my bad english it’s not my main language
Me 18M and my girlfriend 18F have been in a long distance relationship for 4 years due to the nature of our religion and community which makes relationships forbidden or tappo
Yesterday my girlfriend was coming back home from college (it’s in a far city) and was expecting me to come meet here at the station like every time she comes but we didn’t arrange anything nor did i say anything this time that i was coming
It happend that i came home early from college super tired and fell asleep with my phone in my hand and missed her
When i talked to her something felt weird and she was dry texting , it didn’t cross my mind that she was mad about not going to see her.
When i asked her if there was something wrong she said nothing, and we continued on this on and off dry or good texting until she left me in the middle of typing then came back , that sparked everything

That bit happened multiple times before and we talked about it , so i got mad and told her that it makes me feel less wanted when she does this .
Finally i asked her why she is different today she told what i stated above that me oversleeping made her furious

I know i have been yapping a lot but the problem got bigger when we got to the part that she doesn’t say why she is mad unless i ask like 50 times, which is the exact opposite of what we agreed upon when we started this relationship.
And i feel like this could’ve been solved if she had told me why she was mad when i asked the first time.

Now she doesn’t want to change that hapit of not communicating why she is mad or that something made her mad and says that she was always that way
Now I don’t know what to do as bad communication is one way to ruin a relationship
And she doesn’t want to break that bad habit and i honestly don’t know who is right or wrong please i need help
