AITA for only working two and a half hours a week?

now to put this bluntly my ex wife demanded a divorce about three years ago she told me she never loved me and she thoughtthat she and the kids would thrive without me

keep in mind I worked fifty hour weeks to keep a roof over our heads and food on the table and my wife was a bored housewife who had no bothered to get a job despite me asking her repeatedly when the kids got old enough to be in school full time which they had been old enough for full time all days school for years at that point

so I said okay and hired a divorce attorney my wife just wanted to cause me emotional distress by saying that shit she did not actually have paper ready or anything

turned out alimony is not a thing in my state and the default for custody these days is fifty fifty split weeks equal time with both parents joint custody

so we got divorced wife got a hell of a lot less then she demanded thankfully and I quit my job and enrolled full time at a junior college starting in the summer to become an MRI tech pays good money

took me four semesters so a little over a year while studying even during the summer terms and now I stack my shift work double on Sundays and Mondays normal eight hour shift on tuesday so a full forty hour work week condensed into two and a half days and all days I do not have the kids

so I have a lot more disposable income and I get to spend a lot more time doing fun things with my children

my ex wife has been pitch a fit because she has to work when she has the kids so I have the right of first refusal when it comes to child care so I have the kids a bit of than her and thus do not have to pay her screeching ass child support since that situation

as am I the asshole for figuring out how to live my life after my wife decided to be emotional abusive an destroy our family in the process?
