I called my gf a PIG, by mistake... What do I do now?
So I have a great night with my girl, then I sleep at her house and we have a great day. Perfect bliss. At night we go to a movie with her dad and her sister. Her and I have a great time before the movie. We walk around, kiss, hug, etc. Then while we are waiting for some nachos, she comments that I look like the mouse in some new movie coming out, I laugh and then I say JOKINGLY "Hahaha. Well you look like a pig.".
I know, BAAAD MOVE!!! Stupid, stupid move. You don't need to tell me.
The rest of the night she doesn't look at me or touch me or address me, she rejects my call afterward and does not communicate. The silent treatment. So I email her an honest apology with a photo of me and a pig (the photos were very similar and I described the similarities - I was making fun of myself) and leave a nice voicemail. I called her again about an hour ago after work today and she rejected my call again.
What is my next move? I obviously want to make it up to her. I was debating writing a card and dropping it off in her mailbox.
