Should I lie to my best friend?

r/

Hi all,
I absolutely hate lying, but I think this is the one time in my life where it might need to happen

So about 6 months ago, one week after my engagement, me and my fiancé decided to elope at City Hall. The only people in our life who are aware are our parents and siblings. We didn’t want anyone to know because we didn’t want anyone to treat us differently, and we also were kind of ashamed to admit that the reason we were eloping was due to not being able to afford paying for healthcare.

Our wedding is in a year and none of our guests know that we eloped. Including none of our bridal party.

On Saturday night, I went out with my best friend who is also a bridesmaid, and after being extremely plastered, I admitted that we had gotten married. She was devastated, cried her eyes out even after 20 minutes of me trying to explain why we eloped and how sorry I was and finally, she told me that she could never forgive me or trust me again and then left.

I’ve been giving her the week to take and she just gave me a call to let me know that after thinking about it all week she doesn’t know if she can continue our friendship because she can’t trust me. She says it’s been weighing on her heavily and doesn’t know if she can be friends with somebody who would keep a lie like that from her

My fiancé thinks I should just accept it and move on, but my mother was saying that it wouldn’t hurt to just tell her that I was so drunk., I have no idea what I was saying. To pretend like it was a drunk story I made up in my head.

What should I do? I really hate the fact that I told her and if I could go back in time, I would never have told her. On top of the fact that I’m extremely offended that she is hurt over this when it really is me and my fiancés business only. I mean, how more can I explain that this marriage was simply something on paper and that we don’t even celebrate our anniversary or call each other husband and wife. Sometimes we even forget. That’s how unserious this wedding was to us. But I love her and I can’t imagine losing her so I really don’t know what to do.
