Yes YABU
sadly passed away a couple of years ago and left a large sum of money to my husband and kids. My FIL is very into financial management and has virtually total control of the account. We have to get his permission to withdraw any of the money.
Money left to DH and Kids. Later post explains DH has allowed FIL to manage it (& probably invest to ensure it grows)
FIL has been very generous and paid off our previous mortgage so we could move house. Husband hated the previous home, which increased his grief, stress and anxiety. We were happy to move but are now struggling financially with the bills from the new house.
You chose to pay mortgage with what is presumably DH share. Instead living mortgage free or moving to home you could comfortably afford, you've chosen to live beyond your means. Enter FIL who is "into financial management" which presumably means, knows not to live beyond his means!
I cannot get this money out of my head. It is way more than I could earn in 10 years and it is just sitting there.
Is it? Or is it growing a nice nest egg for your kids and their future, as it had been doing before your MIL died?
Meanwhile, I have been a full time at home parent for many years but husband is now pressurising me to get a job to make ends meet. I don't want to disrupt our home life,
especially when all our financial worries would be solved by husband getting FIL to let him have the inheritance he was given!
DH has already made his choice and I bet he goes out to work every day. If you've been at home many years, I bet the kids are now at school. Your financial worries would not be solved by spending all your kids inheritance. Your financial worries would be solved by learning how to earn and manage money yourself.
Should I give up and get a job or stand my ground and insist husband fight for the money?
DH doesn't want to "fight" his father for money, so that you can potter happily at home. He's made his decision clear - you both bought a house that you both need to work, to keep. So work - or downsize.
(Also am I evil?)
You won't be the first person to get obsessed with "free money" and try to reason that it's rightfully yours. You might be nervous of going back to work, you might be frightened of change, you might even just be lazy, but nothing you've said suggests your evil.
