My girlfriend and mother want to send her a text message on her birthday, and I don't know what to send for help.

There are roughly three situations: 1. If you have officially met your girlfriend's parents: Hello, Aunt, I'm * * *. I wish you a happy birthday, happiness, good health and all the best. * * * (Your girlfriend) I will cherish each other. /I'll take * * * (your girlfriend) home with you during the holiday. 2. If we don't meet formally, but know that you are her daughter's boyfriend: Hello, Auntie, I am a friend of * * * (your girlfriend). I wish you a happy birthday, a long life, happiness every day and all the best. 3. If you don't know that you are her daughter's boyfriend: Aunt, hello, I'm a colleague/classmate of * * * (your girlfriend). I wish you a happy birthday and good health
