Quote from what's going on eh ( nice to hear from you again ;-) Just be ice-cold and calm about it. Use his own words and wishes against him. He wants to leave? Then he LEAVES. He doesn't happily get to peruse the rental agencies at a leisurely pace, with you waiting on him at home, asking how he got on. FUCK THAT SHIT. Get the suitcases and bin liners out and start his packing for him.
I realise that sounds terrifying, but it's not. You are helping him achieve his desires, you are helping him follow his happiness. Push him out of the door. Selfish walker.
Made me laugh...but yes after a 30 year marriage I had the same scenario...only he would not confess to an OW. He kept that pretence up for 10 months. The fat twat only told me on Christmas day!!!
I held it together for the kids and gathered them together on boxing day only to find out my sons already knew.
You know OP , so thank heavens to Betsy...the ball is In your court.
See a solicitor on Monday. I interviewed three and went with the one who offered a 60:40 split, who thought it might go 70:30 . In fact it was more like 72: 28.
We had no dependents though.
My little shit was supposed to go 50:50 on the cost of the divorce and while we were waiting for his half he totally filed against me. My solicitor was furious but at least he got to pay all costs and although it put us on a back foot I came out of it well.
Anyway I've jumped ahead of myself. You know. Rip the plaster off. That ten months really took its toll of me while he pretended to make things up. We were going out for meals, cinema etc and then running off to OW at weekends with our precious grandson. ( I love you but not in love with you bollocks)
To keep things as stable as for the kids I'd try to stay in the house. You've got enough on your plate. Move when you feel ready not when he dictates and as other wise posters say don't expect him to adhere to any previously made promises once she has her financial claws into him.
When my exh got with second OW ( after first one had got sick of the pick me dance and married someone else) she steered him towards divorce so gradually all his promises came to an end bit by then I was emotionally and financially stronger.
So yes get all your financial documents up to date , stop them getting their hands on your money and use this time wisely to make the best decisions for you as it will get messy.
But when it's over you will be stronger and the future will be brighter.
I say this from the comfort of my cosy bed, having just had my breakfast brought to me by my lovely husband of nearly a year that is worth ten of the little shit the first one turned into.
It's all to play for.
Good luck. Be strong( you are.) cry when you need too and act in your own best interests.
Put your oxygen mask on first, before you help anyone else ;-)
