What's a bae?
What things to do to make your bae happy when in LDR? :D
First quit calling him/her bae. Next you can send a card or letter snail mail. Love letters are a dying art. Do something to revive that art. Take a picture of a sunrise or sunset and send it letting them know it would have been better of they were there.
That depends entirely on what usually makes your "bae" happy.
If you don't know that ... We can't help you.
