Thanks ponygirl 
Inthequietcoach, what you said makes so much sense. When you're in the middle of it, it is so hard to see that unless someone points it out to you, isn't it!
My lightbulb moments have been;
Realising I sing when he is not around, and don't when he is for fear of disapproval or comment;
Realising how happy I am when away from him;
Finding this thread!! My MIL (who is brilliant) said she thinks I have been detaching for a while. I'd say a few years although in my head I was calling myself dramatic and unnecessary for doing it. When I found this thread and read the descriptions of emotional abuse, I saw a pattern right through our marriage, and a light went out in me.
I am lucky in that I have been living as a single parent for the last two years, with him working away and coming back at weekends. I had a wobble about whether telling him over the phone would be bad; however I knew that if I got drawn into an argument he would convince me I was wrong, he would try harder etc and I would have to go through it all again.
Comments on this thread have helped; in my mind I keep saying DO NOT ENGAGE which is helpful as currently he's trying to force me to discuss details. He wanted to stay over at weekends and I have said no. He can easily stay at his mum's and come here to see the kids, my amazing friend has said I can go there for as long as I like. He tried to tell me he needed to stay for the 'best bit' of the day, bedtime; his involvement in bedtime has mostly been to get impatient and wait for me to get done with reading stories etc so he can have me to himself!
I've got a party to organise for one of the DCs which will keep me happy and make me feel accomplished for pulling it off. Again, he wants to go but I said no, he can make his own arrangements for her actual birthday, because it would be weird and awkward.
He was trying to get me to feel sorry for him yesterday, am I a bad person etc. I don't think he is a bad person but his relationship with me has been horrible. But I'm staying neutral. Have told him to see a counsellor at uni as he was saying he had nobody to talk to. It's so hard not to feel bad! I keep having to steel myself.
Anyway sorry this is really long, I thought if I talked through the process it might be helpful to others? Not wanting to hog the thread, I have ADD and sometimes seem rude or selfish so please tell me if I am coming across like that as it actually helps me not to do it so much!
Haven't actually sorted money out yet. My friend is going to help me apply for Jobseeker's today. I knew I'd have problems (anything like a form is hard for me) so I hope we can get it all done and sorted today
