My ex-boyfriend is married and sends me a message every year wishing me a happy birthday! What is the reason?

Don't worry, your ex-boyfriend just wants to give you a blessing, but he still treats you as a friend. He is married, you should bless him well, but try to keep in touch as little as possible. After all, you were lovers. It will cause pain to your wife, so keep old feelings in your heart. Have a good life. I wish you happiness
