I feel so bad about this and need some help rationalising it. DH and I spoke about going to Italy for our anniversary in May and said it would be nice to invite friends to join us. I found a good deal on a hotel we like and booked it for a week. We talked about having a meal on the last night and inviting friends to that. I mentioned it to my step sister and her husband who DH likes and we had discussed inviting them. She asked me for details and I wrongly? gave her our dates for flights and hotels. She then booked the trip so same dates and same hotel.
Initially I thought that was fine but I told DH (on phone he is away working) and he sounded really gutted as he wanted people to stay elsewhere ideally and just join us for the last night. I now feel dreadful as feel I've spoilt things for DH and obviously I can't retract the invitation to my step sister. Now I am panicking about something I was really looking forward to as I feel I will be stuck in the middle managing being polite and friendly with step sister and her husband and panicking that DH will be annoyed they are going to be around all the time.
I told him we won't be together all the time and he says it's fine- in that way you know it isn't. Have I totally messed up? How can I put this right?
