She deserves it

My girlfriend of 6 years cheated on me with someone she met online. Our relationship was generally happy, may ups and downs may mga pinag aawayan pero overall masaya kami, we go out every once in a while, madalas dinner d ates o kung ano pa man. Pero this past month, nag away kami then I caught her talking to someone on a shitty game she plays online(I won't talk abt the extent). Tas yung malala I begged her to stay even after knowing what she enjoyed flirting and doing shit they did, what they talked about and she tolarated other man's advances. Ako yung nag push na maayos kami kasi that time I thought I couldn't bear life without her on it. Pero ayon as time passes, I realize that she did something I can never forgive. So rn, I'm treating her the best I could so when she reaches the point where she loves me the most, I'll be leaving her for another woman. Petty revenge pero she deserves it. Vengeance is best served cold.
