My son's dad remarried three years ago to someone much younger - she is only ten years older than our son. He has now said that he is leaving everything to her - they now have a three bedroomed property (he already had a two bedroomed property when they met) and he has a good work pension - she will get both. He said that if he might leave my son some cash if he has anything, but that he is likely to spend it in his retirement.

I think that our son will be incredibly hurt by him favouring his new partner in this way and not making any provision at all for him as an inheritance. I have tried talking to my ex but he became very defensive. As it stands, my ex's wife has made no provision for our son either so should anything happen to her the whole inheritance will go to her family who live in another country. They have no children of their own and my ex does not want anymore children.

I realise that he wants to start a new life, but I feel angry at his decision. He will not discuss it with me anymore.

I do not know whether to talk about this with my son as it's such an awkward issue. He was closer to his dad than he was to me, and I'm worried that he will feel rejected by him and frankly will be stung, especially as he has no siblings. At the same time, I don't want my son to only find this out in the future when he would be dealing with the grief of losing his dad.

Can anyone advise?
