Good one Captain!
thanks everyone so much 
Yes noted Mathanxiety, thanks I will tell her it's all coercion, all an act!
Rather handily though and very helpful to my case is that I have a 6 page police statement on him with the countryside police force where we previously lived from December last year stating a lot of the abuse and that I want out of the relationship and he's making it impossible.
So the lovely PO asked for my previous address and has contacted that police force to get all my details and that statement from them.
He's going down people!! Haha 
Well, he's not actually going to prison but you know what I mean! 
I will definitely tell the lovely PO about calling me from the car in front of the kids. If he is up to something like trying to look like a victim in front of them, don't worry I'll put them straight - DD1 is pretty clued up about her father anyway and wants him to move out!
Had some rather unhelpful texts from my mother last night 'you're not calling me, you're ignoring me!' Erm you're not calling me either Mum? Plus I've got quite a lot on my plate at the moment!
I told her I was seeing the police now and for her just not to speak to him if he calls them 'Why the Police?' Because he forced himself back and actually forced sex (I can't believe I said that to her but it's bloody true)
So she relied 'oh my god I don't know what to say, he could go down for 15 years for rape! But then I suppose you do need to get out of there!'
I just said it's alright mum I'm not going to try and get him charged with rape but it's evidence of the hopeless lack of boundaries here and that I want out and he won't let me!
Lovely PO isn't going to take my phone but wants screen shots of the texts - i don't have a clue how to do that so will get googling :)
Have lovely weekends everyone
