We'll always be friends, my dear ex

Wishing you a very happy birthday today!
You may be an ex-girlfriend, but you’re
certainly not an ex-friend.

As long as we’ve known each other we’ve
always had a really special friendship, and
I’m so glad that just because our romantic
relationship didn't work out, it hasn’t
affected our friendship.

I hope that you’re always happy and
that you enjoy your special day today!

All the very best, my dear!
