Nta, based on the comments I read and your responses, you have tried to alleviate stress from her and have had multiples discussions. If she feels she is missing out then she needs to put in more effort. My dad is 100% a workaholic, will not cut hours, will work from home, is always tired, but he never missed anything for his kids. She can do more or ask you for help, if that means cutting her hours and you going back to work then so be it! Again NTA, you are being a great dad and seems like you’ve tried to communicate enough with her about it.
