I feel very conflicted.
DH and I have had a really shit year and could do with some quality time together. Some friends will be in Cornwall over Easter, which also happens to be our wedding anniversary, and have invited us to join them. Our Dd gets on well with their Ds and we haven't seen them for ages so we agreed to go. They have booked, and were going to regardless of whether we come, but we've not booked anything yet.
We had just made these plans when we got a wedding invite - for the same weekend. We'd seen the friends socially, and knew the date, plus we'd received a 'save the date' card, but I had completely forgotten about the wedding. These are good friends and ordinarily I would have loved to go as some other old friends will be there. Dd is not invited, which normally would be a good excuse to get some drinking in with DH, but I am pregnant so can't do that.
AIBU to miss the wedding, which I know will upset my friend, to accept a more recent invite to go away.
P.S if we do go, how on earth shall I word it when letting her down??
