Friend who was meant to act as witness now assumes she will be my MOH - what do I do?

If you decide to demote any bridesmaid or groomsman, be prepared for the friendship to end. There is no tactful way to do that that doesn’t hurt feelings.

I agree with this. You can make whatever choice you want, of course, but there are almost certain to be relationship consequences if you "fire" or "demote" your friend. Only you know if losing this friend will be worth it.

Have you actually asked her to be your MOH? If not, you really haven’t created any sort of obligation to her. Do you just not want to have a wedding party at all? Or do you just not want her to be a part of it?

If you haven't asked her to be your MOH, you don't owe her any obligation to make her one but since she was going to witness your small scale nuptials, I can understand why she would expect this now that your plans have grown, since she will naturally be assuming that she gets the top spot since she was who you asked of all people to witness the wedding.

If you aren't having a bridal party at all, it will be absolutely fine not having her as MOH, but be prepared, if you do have a bridal party she will likely feel disappointed or upset if she isn't in it in some capacity given she was otherwise meant to witness your original wedding, and that might create tension between the two of you.

I can see how she's assumed she's MOH, if she was going to be witness in the smaller wedding. I would think she'll be hurt if you "replace" her with someone else.

I’m in the same situation. Realized that if I wanted her to be a witness, that I wanted her enough to moh. I’m the end it isn’t who you moh is, it is all about who you are marrying
