There’s nothing to suggest she is neglecting her duties or he is picking up the slack for her or she’s spending all her free time on writing. You have just assumed he is doing her share of the childcare @Espressosummer
i work four days a week and parent our wonderful demanding child. Every time I carve out time to do my edits dp finds a way to take it from me. I’ve wanted this all my life and feel so near. today I had a few hours, but he insisted we do something as a family (we have been together as a family since Christmas Eve.) I feel like he wants me to fail
They have been together as a family for days since Christmas Eve and presumably neither at work, and she wants to spend a few hours writing but he suddenly vetoes that saying they need to go out during that time she wants to write. How convenient.
Yes writing a book takes up a lot of time but you don’t know when she’s doing it. Maybe on her day off from work, maybe early before the kids wake up or late when they’re asleep or at an activity.
It sounds like if she had said she was popping out for coffee for a few hours with a mate he wouldn’t have objected. She can very easily put this to the test by saying that the next time and seeing how he reacts.
It is all so wrong and he’s being deliberately unsupportive. All my married author friends with kids - both male and female - have spouses who support and cheer them.
They still work, contribute and do housework, go on dates etc. if it means they have a bit less time to watch tv together or go to bed a little later then so be it. Their partners are not being neglected, they are just being supportive and reasonable.
It’s also sneaky, because he hasn’t outright said he wants her to stop writing and end her agent representation, but yet he is slyly undermining her and blocking her efforts.
If he has accepted she has signed with an agent and working towards this goal, he needs to stop sabotaging. And if he doesn’t accept it he needs to say it openly.
It’s like standing by while your partner takes a job (be it paid or volunteer) you don’t agree with, then when they actually begin you throw obstacles in his way.
