How Do I Stop My Girlfriend From Falling For Another Guy Because Of His Car?

I've been dating my beautiful girlfriend, Akos, for three years. We live in the same neighborhood, and our friendship blossomed into a romantic relationship. Despite our love for each other, our lives have been challenging. Akos had to pause her education and search for a job, while I was hustling at Circle. We supported each other, and I helped her complete her secondary school education.

However, our relationship has been tested by Akos's past mistakes. She confessed to faltering twice, and I forgave her, understanding that people make mistakes. But it seems like history is repeating itself. Akos started working at a shop in her neighborhood, and I thought it would keep her occupied. Instead, she complains that I don't have time for her and flirts with other guys to get attention.

Recently, she met a new guy at a party, and they exchanged contacts. He visits her at work and home, and even drops her off at my place. I'm hurt because she sends him 'good morning' texts and asks about his day, which she doesn't do with me. I feel like she's treating me like this because I'm unemployed and hustling, while this new guy has a car and is good-looking.

Despite my efforts to make peace with her, I can't help but feel like I'm losing her. I love her dearly, and she's very beautiful. Many men are after her, yet she chose me, which means something. But this new guy has come between us like no one else has. I need help to stop their relationship and win my girlfriend back. How can I do this?
