Hi tootired.
This happened to me a few years ago: husband walked out leaving me with our baby son. He cleaned out our bank accounts, leaving me penniless and massively in debt. He'd planned it all beforehand.
The pain and terror was indescribable. I really hear you. It felt like bood poisoning...the adrenalin was constant and debilitating. I also wanted to know when and if that physical pain, the shakes, the sweats, the insomnia would ever end. I drank rescue remedy by the gallon. I lost three stone. I had to battle with the bank. All while looking after my gorgeous baby.
I cried constantly. I couldn't leave the house to start with. It was shockingly bad. It was like a sudden death only I couldn't grieve or mourn him. I found it hard to look at the baby directly sometimes because he had his father's eyes. I felt so sad for my son and was terrified he would be damaged.
I also blamed myself in the early days: I didn't give H enough sex? He'd had a nervous breakdown?
I started to turn a corner after four months of taking small daily steps as pp have advised. I would maybe go an hour or two without thinking about him. I was able to go to the supermarket in the day when it was more crowded instead of the evening. My 2 best friends were able to stop ringing me up every morning and evening to check in. (I had no family support and H's family dropped us like hot bricks the moment he left.)
I started to sleep a bit better.
I cut up all his fancy shirts and ties, and cleared out some of his stuff. Threw lots of his crap away. I started to feel angry.
I was on maternity leave when he walked out but was offered redundancy and took it. Used some of the money to clear the debts. Got a part-time mundane job that involved no emotions or stress.
I would say that once the physical pain had abated I just hung on. The first year of anniversaries/milestones was v hard - our birthdays, wedding anniversary, valentines day, mothers day, fathers day, christmas, NY's Eve etc. But once I'd done them, they just got easier each year.
I have never had another partner, my son is now a teenager and I am nearly 60. I have a small ex-council home which I own outright and have finally found a job that I absolutely love (badly paid but hey so what.) Financially I have really struggled but I'm bloody proud of myself. My son is a typical teen but a great lad.
One weird thing that always helped: I had an open fire in the beautiful old house I lived in when we were married, and I lit it all the time - every evening. It was very comforting. In the house we live in now I had a woodburner fitted. I light it all the time. It makes me feel safe and is so pretty when it's dark outside.
You WILL get through this. You WILL find happy times. You WILL stop thinking about him and your married life. Your children are your lifeline and the continuation of YOU. Please hang in there.
Your H is a shitbag.
