I don't plan to wish my ex happy birthday.
Is there a reason for not wanting to wish them happy birthday?
My ex never did anything for me.
It's understandable to not want to keep in touch with an ex. If you don't want to wish your ex a happy birthday, then that's your prerogative. Even if your ex is upset, you're not in a relationship anymore so there's no obligation to reach out.
Thanks, I'm in a good place now.
That's good. I hope you continue moving forward with your life.
