Thank you all for your replies.
It was a huge error on my part , I thought he would behave as he assured me after many lengthy discussions.
Emotional abuse is what both of us have suffered in the past , and after the death of our mother suddenly ,he supported me hugely over the last eight years.
He apologised for his behaviour in the past and said that he cannot undo his behaviour but he promised to be a good father and Grandfather and has been over the last 31 years.
I think my title of the original post like you say was incorrect.
My Father spoilt the day for me and my sister, whilst he was there.
His waving whilst sat down was an exaggerated sweeping movement , appearing to grab her hand ,which I was made aware of after the second time it had happened , I went to ask him to leave but he had gone.
I have learnt that he really had no intention of celebrating a wedding here and that he cannot be trusted or keep his word.
He risked the relationship he had with myself , husband and son and daughter in law to approach my sister , she is glad that her children could see his true colours for themselves.
Talking with everybody afterwards and today , your replies , I know that this was a truly magical day and everything was perfect.
There has been no contact since , if he does contact me , I will explain that he has let me down and I cannot forget that.
If he doesn't contact me then I am in no rush to speak to him.
He will no longer be welcome to any family occasions in the future.
Thank you all.
