Should I send him a birthday card after break-up?

kiamia
I am wondering if I should send my ex a birthday card (can't text cause don't have his number anymore), it will be a month since we broke up at his birthday.

I am thinking about funny card with just happy birthday, nothing too personal? (We broke up after Christmas and didn't wish each other Happy New Year) How would you guys react?
