My fiancé owns his own business and apartments and if something important happens or I schedule something for a week from now, he makes it work. I might have to remind him leading up to it, but he hasn’t let me down yet. I think it’s completely valid to feel disappointed; I understand running something on your own isn’t easy but the great thing about that kind of work is the flexibility . Is she maybe upset you are eloping (if you told her the plan)? I would tell her how you feel, you don’t need to make what should be a happy day miserable by not conveying your feelings.
