Hi Mo
I might Pm you some more personal stuff, I will! When I get time. Which is lacking in my life.
I sometimes fail but I try to be very neutral about their father. Mine are almost 9 and 6. This has been three years now so they are growing into it.
I say things like (when I'm crying) Daddy has hurt my feelings and I feel sad right now. It's nothing you did and I will feel better very soon.
I also tread a fine line with my DS who has (at age 5) intimated he needs (feels responsible) to make me better so I also say things like, it's not your job to be Daddy in this house. You just need to be you. And then generally tickle or nerf guns come out.
DD is older, she's really suffered but counselling has got her to a good point. So I say things like, I'm so glad you had a nice weekend with daddy., without asking what was nice about it.
If ex yells at me, I say it will blow over, but I'm not going to talk to Daddy on the doorstep about this, it's boring stuff about the divorce. I tell her we have to sort out the money. She accepts that.
Now the go between- yes absolutely. I don't talk to him at all. Not at all.
If he texts I don't reply. I don't email. I don't talk. I don't open the door. I don't look at him (just laugh at his new chavvy shoes) (apologies for using the word chavvy)
This is recent because after three years, £4000 in lawyers bills and paperwork he has torn up in front of me, unless I spend £10k more taking his sorry ass to court, ultimately we don't have enough money to be arguing about money. I can't travel this road anymore, I've been reasonable, sensible, non judgemental to the children. We are both highly educated professional but not rich people. I am way way smarter than him and I have excellent parental support.
He can't match my support, he's shacked himself up with a non educated, older, thrice married non working woman. And it's killing me to try to be a 'good girl' sensible, do everything properly. Because it's got me nowhere in three years.
So yes. Find someone. Let them pass messages along and be a go between. You need someone who loves and respects you but can be sensible.
Make no bones about it thAt you are not willing to discuss anything with him about day to day activities and the lawyer will deal with anything outside that.
AND DON'T BUCKLE! He can't bully you if you absolutely do not engage with him.
Get the middle person to only deal in fact.
DC1 needs school shoes. These have been selected at Clarks for £42.
club fees due for DC2 £55 by 2 June.
Will he ask them for receipts? Maybe but they can factually state back they will supply a receipt once payment is made as per usual for the activity.
You still do all the running of proof, statement, research links. Etc. But he isn't poking you with an accusatory stick. You just supply the details for your go between to type into a bullet point list with no emotion.
I finally asked for help after three years. My mum is happy to help.
