Christ almighty, so Le Slug has taken the day off to 'help' you and has spent it sleeping? When he, err, already gets a full night's sleep while you get up for the baby? And you are the ill one?
Right, what you have here is a godsend, really. It's so far beyond acceptable behaviour in a partner, it's so far beyond being a partner, that I really hope it will get the message across for you.
You're lucky enough to have the house as yours.
You have six wonderful children that you know you can manage alone, or with the other help you already have, because you already do manage that.
Check out tax credits etc, and factor in single person's coucil tax discount. You will see that you will be able to manage financially.
Best of all, you will no longer have to live with the fucking impertinence of this shitbag...taking you for a fool, laughing up his lazy sleeve as you wash, cook, babycare, and work yourself into the ground while he sits pretty, smugly pleased with himself that he's got his little woman right in her place.
Your life would be NICER and EASIER without him.
I'm assuming of course that you despise him. Anything else doesn't really compute.
