My wife and I experienced similar, when our son got married. He lives overseas, where we lived, until my wife, was diagnosed with terminal cancer. As we were both retired, we couldn't live there without income. We had to come home and buy a house here in Scotland. After my wife got over the worst spell of the cancer, we started going to visit our family. Who'd all lived there since childhood. We went out every year at the end of February, when the school holidays were over, as it was much less congested then and the climate, was at its best. When my son told us he was getting married, two weeks, before we'd arrive on holiday, we asked him and his intended, if they could postpone the wedding, until we arrived on holiday. His bride to be, told us, it was the only time, her cousins from America could come. We explained our dilemma, but we didn't even get an answer from her. We had to change our arrangements, to accommodate her. My wife never liked her, from the first day we met the and she detested her from that day on. She was an ugly, fat, coarse girl. I tolerated her for my sons sake. But my wife never spoke to her, from that day, till the day she died. It seemed that her cousins, were more important, than her future husbands parents. I was going to miss the wedding, but my wife wanted to see her son getting married. We went, but there was a rift there, that never healed. I'm afraid I can't advise you, what to do, it's just to let you know, I can understand how you feel
