Oh man am I a terrible wedding guest?

re

My coworker invited me and my husband to her wedding. I RSVP’d on time..... but TOTALLY forgot to put my husbands name on there. I stupidly assumed she’d count us both.

Now I’m having second thoughts. I texted her today (her wedding is tomorrow) and said that I was so sorry, and just to let me know if he’s not on the seating chart and I’d leave him home. I told her no stress and that I just wanted her big day to be perfect, but she hasn’t responded and I feel like an ass.

Did I just become the nightmare guest trying to get her Plus 1 to crash the wedding?!? I totally won’t bring him if he’s not seated!
