Entering the fray. My XH was required to get an insurance policy on his life in a certain amount with each of our children as beneficiary. He's also required to get a term policy for the amount he owes me in spousal support, in case he dies during that period. I already had a policy on his life with me as the beneficiary -- I am the owner and I'm keeping the policy, and the payments.
He does not have a policy on my life, but his lifetime expected earnings as a lawyer, and his expected inheritance, obviate the need for a policy on me.
I want to speak to the issue of your house. I got the house and all the equity in it. I make all the payments and upkeep. He walked and kept on walking.
There was only one point where he mentioned the equity -- I was DBing my heart out -- and after I nearly threw up, he backed off. The adultery evidence didn't hurt, either. Helped him be clear about his priorities!
Many women hold on to the house but then are unable to make payments because they have inadequate income. Look at this closely, Liv, and figure it out. I agree that your fellow could get squirrely, but a court order for support is a court order. If he violates the court order, the court can take care of him.
The one caution I have is that a narcissist can take your self-preserving actions as challenges to himself -- watch out how you behave and work to de-escalate (if you can.)
