Good move. You took a possible tax hit from liquidating assets, into a support/alimony payment which is a tax deduction for you, and taxable income to her. Bravo!
My ex took a lump sum because it was 100% tax free and on a tax basis worked out better for her, and met my criteria not to have to carry her lazy ass one more day than required.
It worked out great for me because I was a hair away from going on disability (the stress was causing seizures a few times a week) and her affair was the BEST thing to happen at the BEST time. She is a very needy person, so it was a lock he would charge in on a white horse and save her. As it eventually turned out he was so paranoid she would go back to me, he hacked her email and cell phone and got caught…….
When we made a settlement offer, she simply took it. My attorney (she was great and has a reputation for being very very tough) told me to shut my mouth and let my star struck wife bring the whole thing in for a landing…..she did.
She now lives in a house she can’t afford, and I really don’t think she thought the fact through she now has no health insurance, car insurance…..zippo! I actually laughed because she she amassed THREE speeding tickets in a year (yes, rules of the road don’t apply to her either lol) that our car insurance company dropped her a month after we were divorced. Into the high risk pool she went at the cost of $5,000/ year. My insurance went down by $1,600….ha ha ha……Not to go on and on, but she called me up and begged me to keep her on my car policy. If you follow through with a divorce, the best part is the word “No” is actually a complete sentence. lol
In truth, she is sitting on a slug of cash, so she can afford it, but like when we were married, that is “her money.”

I have to say although my retirement has been stunted, I got a really really good deal. My stress is down, seizures are under control. I’m pretty calm and happy, and I have been seeing a really nice woman who shares many of my values and interests who is a lot of fun…….

All the best, and it will be one way or the other.
