We had the same experience with my husbands daughter when she got married, the grooms family were very stand offish, never spoke to us, we had all kinds of upsets from his daughter about how they were overpowering her, his mother was making all the demands. We stepped in and supported her through all the arrangements and did our best, when it came to wedding day you could cut the air with a knife, his lot were very unfriendly and we were out on a limb. My husband sat at the head table with his daughter and I was placed at a table with my back to them next to some stranger. Her mother took over although not been in her daughters life for years. We were very shocked at how we were treated and just stayed cool so as not to spoil the day. Having spent months organising the wedding we were now given the cold shoulder, his daughter had gone cold was very rude to us on the day and I did not even get a thank you from her.
We visited them after the wedding hoping all would be well and we had the cold reception from his daughter, still cannot work out what was wrong. then finally a huge fall out and row and a 5 page email from her husband telling us how she has suffered and him telling us what terrible parents we are etc etc abusive was mentioned and that from now on his wonderful mother will be taking her on as her daughter. well quite frankly she is welcome. I feel used and betrayed, have now cut them out of my life and will not have them in my home. I feel her husband caused the trouble so he can control her, no one likes him and quite frankly they are off my xmas list. It will not end at the wedding it will get a lot worse.
