How does this sound?
"Instead of being inconsiderate and ignoring you back, engaging in childish games, I'd rather be upfront and communicate why I'm no longer interested in talking to you. Ignoring someone, especially without an attempt to apologize upon your "reappearance," is just rude and juvenile, and honestly, it's emotionally manipulative. I don't have time for men who disregard women in such a way and attempt to make up for it with the word "beautiful." It was fun while it lasted. I wish you the best in the future. Goodbye."
