My ex-boyfriend is going to have a birthday, and I want to send him a blessing message. He should have a girlfriend, right? Is it okay?

Absolutely not. It's not necessary. If you meet him, smile and treat him as a friend. Don't be too stingy and ignore others. But today is my birthday. Think carefully, some people's birthday wishes are unusual and sensitive, and you are a sensitive identity. It's best not to disturb him, so as not to let your memories and his memories flood. Just bless yourself silently. Don't show up.
