We had 2.5 years between when I ER'd and when DW retired full time. My early retirement was sudden and the timing unexpected (I got fired).
After a few hours of being dazed, I realized we were close enough to FI to call my termination my early retirement. In discussing our finances and FIRE plan with DW, we decided she could join me at any time and started making plans to quit.
As it happens sometimes once you no longer need a job, she was able to negotiate fat raises and bonuses to retain her, then a five week paid sabbatical my first summer of ER so we could do a big vacation. Then they promised her another 3 months paid sabbatical if she stuck around till the following year. She took it month by month and managed to make it to the next summer (and picked up another fat raise and bonus in the meantime). Shortly after returning from that second sabbatical, she put in her notice at which point they moved her to part time work from home for full time pay as long as she wanted. That lasted six months until she quit this February.
The whole time we were taking it month by month and she knew she could quit whenever, so there wasn't a lot of stress or expectations on her. It was relatively easy money with a clearly defined escape route. I'll confess to the tiniest bit of resentment directed her way because the work schedule slightly interfered with possible last minute travel options (though kids in traditional school were the bigger impediment).
Along the way there was probably some resentment from her since I had a very nice schedule.
But I took care of just about everything (other than folding and sorting laundry) including waking up before 8 every weekday to get the kids to school then picking them up in the PM. I had dinner ready every day to accommodate her schedule. Grocery shopping and other errands I took care of during the day. Took kids to the doc and dentist appts. Basically stay at home dad, maid, handyman, auto mechanic, gardener, etc so all she had to do was show up to work 20-40 hours per week and collect a pay check.
Going from two of us working to one increased quality of life greatly. Her evenings and weekends were once again free (other than the laundry folding lol). Walks in the park, attending evening events with the kids or around town. Having time to watch a movie or play some games during the workweek instead of dealing with kid-related stuff.
After her ER, it's been even better.
