I just received an email from a friend who, due to financial reasons, has to change her RSVP and can no longer attend the wedding next week. I feel bad because she's not obligated to give a gift, but feels like she does in order to attend. How should I respond? I don't want to force her to come, since she's made up her mind but I would like her to know that we don't expect anything. We haven't given the count yet so it was nice of her to let us know, but how should I word my response? i'm torn.
