Forget to show up to a date, how do i recover?

So, I messed up. I had set up a date with a woman, but I completely forgot to show up. It’s been two weeks now, and neither of us has messaged the other since.

I know it’s on me to reach out, but at this point, is it even worth trying? Or have I burned this bridge completely? If I do message her, what should I say to not make things worse?

Any advice would be appreciated.
