There’s always going to be drama when money is involved.
Here’s the fullstory: “My ex and I were together for almost 20 years.

We never got married because it never felt necessary, and we were child-free.
I had problems with birth control, so he chose to get a vasectomy.
I found out that he cheated on me three years ago, and I left him.

He got with his adultering partner.”
“Six months later, I heard that they were married.
Sure enough, we are very happy, and we love our little family very much.”

“I was contacted by a solicitor to tell me that I have inherited my exs estate.
He had left everything to me besides some to his parents' pension and his nephew.
“Now, his wife and parents are very angry and demand that I leave them everything.

Would I be the asshole if I kept it because that is what I want actually?
And what he wanted.”
A gift freely given is yours to keep.”

I think he passed with regrets and wanted to make it right.
He left that money to you on his own accord for a reason.
Fundamentally, a person who engages in an affair should not stand to profit down the line.
Keep the gift and enjoy your life."

“Flip the script, they would give you nothing.
Up to you if you want to keep it or ration it out.
As others have said, get a lawyer and a paternity test before you make any decisions.
If you do decide to give the child any money, do so via a trust.”
