@Sendwineplz I don't buy that. I do believe that you don't get the opportunity to explore things you like and as women we can get stuck into a cycle of mothering and wifing, and losing who we are, all while facilitating our partners and our children finding themselves and what their interests are. I say this from experience.
I had a big to-do with my husband about how I don't know what I even like any more and he agreed to give me some time every other day to do what I want without interruption. And I didn't know what to do with myself for a few weeks because I, like you, felt like the most boring person ever.
But I decided to use that time to do something I enjoy, write down ideas for a business, research sourcing products etc and I started to really look forward to that time alone because I was doing something for me that benefitted only me.
But I do stand by what I say. It's possible to have 2 working adults in a relationship, with no or minimal childcare costs if worked out correctly.
Flexible working applications can be applied for after 6 months of committed working, and you retain the right to return to full time hours at any point.
So that means you temporarily go part time, or change your hours and after your husband has worked for 6 months, you can come up with a plan to fit his hours around your full time hours and both of you have an income, more financial freedom, both of your minds are busy, and the children are always cared for.
It's not always that straightforward but it's not impossible to find a situation that works for you both.
If he gets supported for his project, and like you said he sometimes doesn't know when to stop writing, so he needs a time limit not only to stop him burning himself out but so you can enjoy finding something for yourself or as a couple. He also needs to support you, and that support first starts with finding out what you like to do. It might not be instantaneous, but you can't keep living like this.
Everything he's said so far is an excuse to ensure you look after his needs because he's all that matters in his world right now and he needs to wake up.
