My ex confessed to me part of the reason she ruined our marriage and was hoping I would change? please read below?

The truth finally shined from her after all these years we were together , she said it’s because I am not a fixer , basically she was implying that I should be every occupation at one time , A plumber, a carpenter, an electrician , a builder a mechanic , and interior designer etc. I agreed with her that I am not all those things , but I do my best when things break in the house and if I don’t know how to fix something , I will YouTube it or I will hire someone that can fix it. she knows I am not lazy and She knows I am a hard worker and she knows I achieve most of my goals and continue climbing the ladder, but apparently I am not good enough in her eyes. Do you girls’ expect your man to be all of those things? I feel betrayed cuz I never expected her to know everything and never held her accountable for it. Am I not a good partner?
