I think lifetime alimony has always been a bad concept but sometimes SOMETIMES it is appropriate. The example? A cardiothoracic surgeon marries a medical assistant and they have a marriage for 30 years and then he decides he wants a young hottie.
Why can't she just support herself, men cry? Um, she gave up everything to devote herself to the partnership, that's why. He gets to stay in the Mansion on Snobgrass Hills and she gets an apartment on the other side of the tracks? No.
And I am a man saying this.
That said, I am more of fan of "restitution alimony" because of what the other person said - you are "tethered" to this person the rest of your life. When money exchanges hands on a weekly/monthly basis, it's just room for so many problems.
I would explore WITH YOUR ATTORNEY the idea of converting the lifetime alimony into restitution.
I'll tell you why you are at an advantage and the guy's replies here back me up. . .men just want out. They resent that monthly check so much. They'll pony up, maybe to your advantage to let him go. So think of what his lifetime payout to you may be, make an offer where you could invest it and come out nearly even or maybe even a little ahead. (start negotiations there- ahead).
This is just a business transaction, nothing more. But no, any attorney worth his/her salt is not going to just let you walk away because he wants to call a wahhhhhmbulance. Bad decision.
Be a Master Negotiator. Like Trump.
(who men tend to adore) And be ready to walk. Always be ready to walk.
