Dating culture

Hi everyone, I met an Ethiopian girl on tinder, we agreed on meeting in person and everything went as planned. Food, drink, leisure (parks), ride was all on me. We met multiple times. I paid her ride coming and going back home each time. I expected at least a little gratitude or just saying thanks for paying. But for her it was like self explanatory or natural. I am habesha but grew up in the western world, if it comes dating my experience was either sharing or everyone paying for himself, and this was only for the food.

The last time we met I paid only for our food not her ride, I actually wanted to but my ordered cheffeuer arrived earlier than hers(separate directios), I had to hurry and forgot leaving her money. I guess she is mad now, not replying all day, she used to text. I don't wanna lose her but I want to understand her.

My questions would be:

Is her being mad, because of that one ride that I didn't pay, a sign she is only after my money? Is the Ethiopian dating culture "only the man pays-it-all" mentality?

Shows little physical affection, I can hug or kiss her on her cheeks but she is most of the time apathetic. Is this normal?

Also she emphasizes communication matters to her but says little, is this normal? She starts staring something else in the middle of a conversation, little eye contact and kinda absentminded and in deep thinking at times. I was worried she doesn't feel comfortable around me.

I know everyone is different and she is unique but can you guys help understand her more by answering this questions.

Thanks for any kind of helpful answer.
