How to get along with a person who spends generously on himself and pretends to be poor to his friends?

I met such a woman. We had a good relationship at the time and had been my best friend for three years. She always cried in front of me. Not to mention, although I am not rich, I am still relatively well-off. I always like to buy some food to bring to her when I go shopping and go back to school. Later, after I graduated from high school, I went to their house to play with her, and I discovered that their family was actually better off than mine, just a little better. But I felt sick at the time. She had an iPhone at the time and told me that she had bought it two years ago when it first came out. At that moment, I felt sick not because her family was richer than mine, but because I felt stupid. You always cried poverty to me, and I always bought snacks for two people, even if the food was expensive and I couldn’t afford it. We always share the food together. Every time she buys it, she always praises me, saying that she loves me the most and that I am her best friend. She says that I am a wealthy person and begging for support. In her eyes, it turns out that I am just a victim. Saying this is not to say that people who cry about poverty all day long cannot have deep friendship, but that people who cry about poverty all day long but always take advantage of you and never help cannot have deep friendship.
