I asked him directly what he plans to do with the money and he said invest it.
Your very first post, yesterday.
In your 2nd post you said you assumed he'd invest it in pensions so he could retire at 60.For those asking what he’s going to invest it for, I’m
not sure. I’m assuming it will be for retirement. He’s made a point of saying several times that he’d like to retire at 60.
You went on to say you had little in savings, and that it made sense to invest it.
I don't understand how you can forget this overnight.
You don't have a money problem per se. You have a communication / marriage problem. Your values seem different.
Do you ever sit down together and plan your finances?
At 45, hoping to retire in 15 years, you need a plan.
You should both get pension predictions, state pension predictions (although the retirement age is likely to rise to 70 by then.) And work out what you need as income through pensions.
The current advice is, for a couple, £25K for a basic lifestyle, £42K for a more comfortable lifestyle and £60K + for a more luxurious lifestyle.
You should decide if you can overpay your mortgage and by how much or use his inheritance to clear some of it.
And as your kids may be going to uni in your 50s, you need to consider if you can help fund that- current student loans do not pay for accommodation. (Many years back we were paying £700 per month ON TOP of our own mortgage to fund our kids at uni/ accommodation.)
Some financial planning is needed before a holiday in Florida.
