Be kind to yourself. This will be hard and likely triggering given what happened with your parents.
You are strong. And you will survive this and show your DDs how to be strong, independent women.
First, you need urgent therapy to help you vent and process if feeling you want to harm yourself. If you can’t afford a few sessions, could a relative or friend help? If not, some schools can offer free therapy referrals to parents, so ask the school. Get a referral to talk therapy from your GP, though it could be a long wait, it’s worth having your name down.
Second, do one thing to make you strong. I chose swimming. An hour once or twice a week. It made me physically strong, helped tire me so I slept and the space and light helped me mentally too. Every stroke i imagined pushing him out of my head to get rid of all the inner rage.
Third, get legal advice. A good family law solicitor or Citizens’s Advice. To find what you’re entitled to and your financial options. Don’t expect him to do the right thing financially.
Fourth build a support network. Your friends, mums of the kids’ friends, work colleagues, the school, a local childminder, older neighbours. People who can trust look after the kids for you when you need time to yourself or to work. People who you can meet up and have fun with. Winter walks, movie nights etc. Who’ll invite you over for the odd lunch or dinner. Don’t be afraid to reach out and ask. Lots of mums have been through this and will get what you need.
Fifth, set some routines, e.g. Sunday mornings before lunch you all go for a walk somewhere lovely in nature: stately home, park, local walk through fields or woods. Take peace in observing changing nature. Wednesday evenings you all play a board game or cards. Friday is movie night with homemade popcorn etc., Saturday, the kids choose a recipe and you all bake flapjack or a cake together. Routines fill the space, give you an anchor and the kids will love it.
Get yourself some good books for the evenings when the kids are in bed. Biographies of strong women who’ve triumphed over adversity, gripping thrillers, whatever floats your boat. But something to lose yourself in with a cup of Horlicks and a hot water bottle in bed!
Treat yourself to little luxuries. A nice perfume to spray on every morning. A new lipstick, some lovely herbal teas, a nice house plant to nurture, new underwear. Take joy in tiny things.
You’ve got this. You are strong. You have experience to guide your kids.
Forget about him. His loss.
