Should I call?

So my uh...er...ex boyfriends birthday is tomorrow.

I say it like that because I recently lost my job and had to move out which meant me moving out of state... (NY to NC) I literally just got here 2 hours ago.

His birthday is tomorrow....

Now I know technically were not together since maybe 3 days ago

Do I call him for his birthday and wish him a happy birthday? Text?

I didn’t want to leave but I sort of had to and it was this unspoken thing that we wouldn’t be together anymore because of the move.

Thoughts? Yes or no to call lol
