My ex-boyfriend, who hasn't contacted for two years, sent a birthday wish to the girl on the night of her birthday, wishing her good night. Is it polite?

It is impolite to send birthday wishes. If so, why not last year and this year? This at least proves that your ex-boyfriend misses you very much.

If your ex-boyfriend just misses you, I think it's normal. After all, you should be together for a long time. Although you broke up, as ordinary friends, he didn't have much blessing for your birthday.

There is another possibility. He just wants to get back together with you and care about you in this way. He's testing you. Look at your attitude. If you feel the same way, don't miss this opportunity.

good luck
