@larksrise congratulations - I mean it.
Pushing through that first obstacle is tough.
You have done it, it’s over.
Everything else will happen now.
Hope this is ok?
I do not want to be negative by adding practical advice to the emotional advice, but your OP does not say how far you are with the process.
Your immediate emotions:
How do you get through it? It is a form of grief and like grief, you are kind to yourself. You put one foot in front of the other.
Sometimes you take each day as it comes, sometimes it will be minute by minute.
This sounds silly; a friend gave me this advice when I ended my first marriage I was in my 20s! On the days when you are feeling low, or negative, or doubting yourself and everything feels insurmountable; make yourself a tick list in your head I am not infantilising you, this does work! So: got out of bed mentally that’s one tick, showered = 1 tick, teeth brushed another and so on.
It stops the day from feeling completely negative and focuses your mind on the positive things you are achieving, however small.
As much as you can, allow yourself to feel all the feelings.
Can you take a few days off to get yourself over this first hump and concentrate on you?
The immediate:
Being completely honest; I am concerned when you write that he vacillates between lovely and vile.
Is he still in the house with you?
Are you safe?
If you are not in separate homes how quickly can you arrange to be?
The practical:
Do you have a solicitor?
If not, find one locally who has a takes-no-shit reputation and get an appointment before the end of this week.
They may be expensive but, particularly in the case of divorce, good legal advice is worth every penny.
Do you have details of all of your financial assets and liabilities?
If not, find everything you can and make copies.
Ensure you make notes of all of the reasons you have decided to end the marriage.
You will need these for your solicitor and it will help to look back at them on days in the future when you might be having a wobble.
Your daughter:
Explain what is happening to her in an age-appropriate way.
Be as honest as you can, with the emphasis on how much you love her.
Be clear that she can talk to you about anything at any time.
DD may well need comfort too, 9 is old enough to ask her what she wants to do to make herself feel better.
Don’t be afraid to ‘spoil’ her for a while, I mean in the sense of giving her time and attention.
Devote any spare weekend time to doing things she enjoys and let her choose the activity; baking, building Lego, snuggling under a blanket to watch a film or read books.
You know DD best and you will know what she likes to do.
@redpheasant all I can do is draw on my own experience and that of my friends and family.
I spent the majority of my 20s married to a truly awful man, the only thing I regret is that I didn’t leave him sooner.
You do have the courage, I wish you all the best.
To anyone reading this who is going through a breakup now: sometimes you really will feel like that phoenix, other days you will feel like a pigeon.
It does get better, day by day, month by month, you can hold me to that.
Sending everyone the best.
