I'm lonely but I don't need a girlfriend because being single makes you appreciate peace

Now hear me out. In 2012 I was in a relationship with a female that brought me nothing but trouble, pretended to be suicidal, made out she had mental problems and turns out that she was cheating on me. She is a textbook attention seeker, and I did have a 10-year relationship with her on and off. It got to the point where I was stress eating, lack of sleep, depression caved in, and when I caught her cheating on me. I used this as an exit to get out once and for all. I fucking left the country like a bat outta hell. I came home, and it took a few emotional years to get over her to the point where I now appreciate being single as a choice.
