As other people have said, there's a reason you don't make big decisions in the first six months!
I've had two (low) 6-figure inheritances and for the first six months didn't want a penny of either of them. It's tainted money and a reminder of what you've lost.
After that, the first one I ended up spending on my degree, driving lessons, a car and then house deposit. All would have been okay with the person that died I'm sure.
My DM then died a year ago. My disabled sibling is remaining in her house but that was the right decision for us even with the benefit of hindsight.
The rest I have put into investments. However, I've also paid off our loans and credit cards and booked a holiday for our family for next year (somewhere my DM loved).
I recently had to reduce my work hours drastically and we'd have struggled with our financial liabilities if I'd given it away as I originally wanted to do. A lot can change in six months and I'm glad I waited until I was thinking more rationally before doing anything with it.
You need to get across to your DH that now isn't the time to make the decision and he should review it in six months to a year.
