Yeah it's definitely an inheritance.
But only the most tight-fisted, mean-spirited arsehole would keep the money to themselves after being married 20 years.
I think this would make me SERIOUSLY reconsider the marriage.
Me and DH had been married 4 or 5 years, when he got an inheritance of £15,000 in the late 1990s, from his gran, (probably about £25,000 in today's money,) and he put it into our joint savings account, and booked us a cruise for our birthdays - they are a week apart.
He also bought me a bunch of gifts, including some lovely jewellery, a new pushbike, some new clothes and new shoes, and an expensive perfume that I wanted but wouldn't have bought myself. And he left the money in the joint savings account.
It didn't even cross his mind to keep the money to himself, and we had only been married 4 or 5 years, and together for about 7 years.
So YANBU to be pissed off at him keeping the money, and to think he should share it.
