We have children and grandchildren together and have been together almost 40 years. We are not married. We have had a difficult relationship at times mainly because he is deceitful and selfish. We do however get on on a day to day level. I wanted to leave him in the past but for various reasons, young kids then elderly parents it seemed better to stay. I had thought that after him being unfaithful then very remorseful 10 years ago we had reached a good place and could grow old together in relative harmony. I have now found out that he has been lying to me for a very long time and is in a relationship with someone who caused me and my family a great deal of pain in the past. This is a complete betrayal. Not because of the sex but because of who it is. I feel that he has no respect for me or our relationship and has treated me with contempt. So I have told him it is ended. He is very upset and concerned that the rest of the family will turn against him and he will be cut out. Frankly that is on him. He will have to buy me out of our house. I am financially independent so am not worried about how I will live.
What I am struggling with is how to tell my children and how to manage Christmas which we were supposed to be hosting. I don't want to wreck everyone's Christmas at this late stage. Should I not say anything until after Christmas or should I speak to them and let them know and they will need to sort something out for themselves. What a bloody mess.
