Invite Heartache

I was going to comment something similar to 74jax.

We're getting married this year and I won't be bothering to run around and find people from years ago.

I agree with 74jax, just tell her that you had limited numbers and were working to a strict budget. You can always catch up with her after the wedding.

You shouldn't let it bother you, ultimately it is your wedding. If she's a good friend she'll understand that she has not been excluded maliciously.
