"C'est ma petite copine."
Why do you care? I'm French and if your girlfriend is french, just pretend ! Gawd you just want to say it so you can impress her and you'll get her.
Je t'aime
petite amie
putain salope
One says "girlfriend" in French as "copine" or "petite amie."
The way to say "I live my girlfriend" is Je Vis Ma Petite Amie and "I love my girlfriend" J'aime Ma Petite aime
To say "be my girlfriend" in French, you can say "sois ma copine."
I believe that would be Ca va, petite amie? My french teach told us that...
You can say "Ma petite amie m'a largué."
la petite amie de mon frère
j'aime ma petite amie, j'aime ma copine
"Boo boo" has no translation in French. You could replace it with "boyfriend" or "girlfriend" Goodnight my boyfriend: bonsoir mon copain Goodnight my girlfriend: bonsoir mon amie
