If I get away from my wife, will I still be a soyboy?

I'm 30, and I've been married for 4 years. I've been together with my wife for 8 years. And I've been a soyboy for 8 years. I met my wife when I was a young man, and I immediately lost all my hair. My wife took care of me during this period, and I immediately fell in love with her. I became an emotional crutch for her. A close friend of mine once told me, "She's a bad woman, don't marry her, she'll ruin your life." But I didn't listen, I was in love. I married her, and now I realize that my friend was right. At first, my wife was perfect, but over time, I began to notice that she was lying to me and manipulating me. I started to feel like a dog on a leash, unable to make my own decisions. One day, I discovered that she was having an affair with my best friend. That's when I realized that I was just a backup husband. I feel like I've been punched in the gut, and I don't know what to do. I've always been a good husband, but now I feel like I've been deceived and betrayed. I don't know if I can save my marriage or if I should leave her. I want to know if I'll still be a soyboy if I do.
