Hoping, I am almost in exactly the same shoes that you are: similar net worth (but one million in primary home), similar income requirement post FIRE, just a few years older at 47, golden handcuffs are similar (some years twice yours and some years about 75%). It seems there is also the potential for a sizeable "going away gift", depending on how things work out, but that is not guaranteed. My non-home assets are primarily in my taxable account.
If I were you, I would stick it out another year, and at the same time, learn to be like a duck...let the nonsense just roll right off your back. I am personally working on (yet again) adjusting my attitude to be able to do just that. Why? Because at my age, 3% is more comfortable than 4% (2.5% is better for you at 41, I agree). I have episodes every once in a while that remind me why I want to FIRE, and had another just last friday. But, you know, being 100% assuredly FI and being able to do exactly what you want when you want, knowing your parameters, is probably worth a year or two of letting the "water roll off your back" like the duck. I think it would be better than "worrying" all the time that you weren't going to make it because you bailed too soon.
So, barring any physical issues being presented because of not taking the (very) early out, I would advise stikcing it out just a little longer. A year for you probably means at least $300-400k new money to invest, two years would be twice that. Personally, I'm sticking it out at least another year, probably two, and maybe even three.
Good luck, hoping!
