And when you've got some legal advice here's my advice to get you through the next six weeks; (I'm single skint and have three aged 9, 7 and 5) until you can get him to leave;
really try to focus on the positive and what you can do on your own with them, rather than saying that you can't drive, can't afford things, can't go to disneyland. Anyway, who'd want the stress of taking three away alone? YOu can have far more fun and an easier time at home
Try to get them out of the house every day, even if it's to the local park. Pack a picnic that they can help you make.
force yourself into that car and drive every day, even if it's for a short distance; if you're going to end up as a single parent you'll need to be able to drive . You passed your test so you can do it.
Perhaps invest in some cheap scooters and take then all out each day - the novelty will take a while to wear off and wil be a lot cheaper than disneyland!
Do you have any friends with young dcs? Could you meet them in the park or plan something together/ Or invite some of your dc's friends around to play and vice versa to give you a break.
Do you have a garden? You could get a cheap paddling pool, balloons and sand etc for the two young ones.
Could you start to let the 9 year old stay at home alone for an hour or two whilst you do something with the other two? My 9 year old loves this but he is quite mature
Decide on a bedtime for them and stick to it; otherwise you will get worn out. Perhaps you can get your dh to sit when they are in bed so you can go for a swim/walk etc. Expect nothing from him so that if he does help it's a bonus
Seek out other lone parents in your area and try to make plans with them to do things
Stock up on Dvds/books/pens and colouring books from charity shops
Try to stop comparing yourself to people who you perceive to be happier/better off than you - everyone has problems, they may be heavily in debt for all you know.
Make doing things cheaply a bit of a challenge and an adventure and try to take pleasure in smaller treats , such as an icecream or fish and chips in the park. If you are positive your dcs will be.
