Hi whyMe2014
You are completely blooming awesome. Your strength, courage, determination and humour shine through here. You are amazing. 
You are me 3.5 years ago, but I sure wasn't coping as well and hadn't come as far as you have in 2.5 months. Perhaps that is partly because you have had great advice from everyone on this thread (I wish I had had MN when it was happening to me) but you are the one who has acted upon it. Well done you.
It amazes me how similar stories can be. It's like they follow a script!! Cars especially seem to be a factor of fuckwittery (that whole Freudian thing must be true, surely)
It is a roller coaster. You have to ride it, even when you feel sick and want to get off. It has to be ridden to the end, but when you get off....oh what you will have accomplished and NOBODY can take that from you.
I am going to challenge some advice normally given about putting the kids first at all times. Yes, you need to put personal feelings aside when making access arrangements unless there are some good reasons for concern (as you seem to have). However, I made myself very unwell just only thinking of the kids and not myself. I had an epiphany about 3 months in and realised that if I didn't take care of myself, I wouldn't be fit to take care of the kids (emotionally, physically and financially). I try and rank all 3 of us equally whenever possible. DD11 and DS8. It works for us.
More fuckwittery will come. That is certain, but you are well on the road out of there and to a place where his actions will not cause a tornado in your life. Prepare yourself, watch for the warning signs and brace for it, you will survive x
IT DOES GET BETTER. I promise you. My controlling STBXH (despite him being the one demanding the divorce) made no actual moves to get it finalised. I finally gave up waiting in August, did all the paperwork and got the news on Monday that I am now officially divorced YIPPEEE!!! My hands shot up, I punched the air and actually danced a little in my seat at work, entirely involuntarily!! My workmates congratulated me. It was a fabulous moment. Actually, that makes him XH now doesn't it!
WellWhoKnew you are an awesome lady too. Your thread is genius and advice is solid.
I wish both you ladies well on your journey - you deserve nothing less than fabulous. Please bear that in mind. Always.

P.s. Tuna/Hoover/fishwife - am loving your work!!! LOL indeed I did!
