“He will support the DC but he wont support me.”
Tough shit. The court will decide that, not him.
Listen very carefully. You are married, which means that what’s yours is his and what’s his is yours. If you divorce you are entitled to a fair share of everything. Not just for the kids. For you.
You have given up your career for seven years to look after his children. If you hadn’t done that, he would have either had to give up his job and look after them himself, or spend a significant amount of his earnings paying for childcare. He has more money in his pocket because you didn’t work. Everything he earned during those seven years was partly earned by you and you are entitled to a share of it.
My advice to you now would be to find every document and every piece of paper, every insurance policy or pension statement or bank account you can and take copies of everything. Take hard copies and store them at the house of someone you trust, and take electronic copies and store them somewhere safe, such as on a USB stick or in an encrypted online account. If you do end up getting divorced, you send every last document to your solicitor. That way, if he tries to hide his assets, you will have proof that he hasn’t disclosed everything.
If things start getting nasty between you and he says anything he shouldn’t, about the house or the kids or the money, write it all down in a diary or maybe in your emails. If you send yourself an email with the details any time something happens, you’ll have an online record of it all with dates and times.
Don’t say anything to him. Don’t tell him what you’re doing and put the wind up him, otherwise he’ll start hiding stuff before you know it. Just get your ducks in a row.
And don’t worry too much about jobs at this stage. It would be great for you to be able to support yourself and have a bit more money coming in later, but for now, focus on making sure you get your fair share of your shared marital assets.
