So you feel like you won't have any chance for a break.
You could do any of the following:
- Use a holiday club occasionally. Some aren't expensive.
- have the occasional day to yourself, whilst their perfectly good other parent looks after them.
Both are perfectly viable, perfectly reasonable solutions. But you choose not to.
You sound like you're in a fully stocked kitchen complaining about having no food.
The difference (and massive perk) that you have being a teacher is that you can use holiday clubs to get time to yourself, rather than using them to keep your job. Most of us are so short of leave that we couldn't dream of using holiday clubs to have time to yourself. Your can, but choose not to (and then complain about not having that time to yourself, that you've chosen not to have).
I don't mean going out for whole weekends (then there's nothing wrong with that occasionally either), but for a morning, or a few hours in the afternoon. And no, that's not a 'proper break' but it's what most of us get in reality.
Personally, we'll be tag teaming one of us being off, both of us being off for a holiday together and using clubs. I'll be looking after kids in the day and then making up time for work in the evenings.
I think what would improve your life a lot would be to get more confidence in having your children together (and the same for your husband).
Ps: yes, having two young kids is hard and relentless. The idea of weeks to yourself with neither work nor kids is just a fantasy to most of us.
