My partner is a startup CTO. He works all day, takes a break for dinner (which to his credit he cooks) and then after our 3yo daughter goes to sleep he goes back to his desk and carries on working. At the weekends he often decides last minute he won't be doing things we had planned because he's too exhausted. When I try to talk to him about how lonely I feel he gets defensive or shuts down and goes silent. I'm the main earner and do the majority of the childcare. Does anyone else here feel like they're a widow to their partner's tech career?
