HelpMe, we saw Cars2. It seemed to do the trick with the DCs (and me) we all came out a lot more chilled.
Got home and DH was obviously peeved that we'd all just gone out and left him for the afternoon. Coupled with the fact that I did not make him dinner last night (only for me and DCs), he was pretty pissed off. Enough in fact to start talking to me again. I said that I was not doing 'wifely duties' for someone who shouted at me and was mean to DC2 yesterday.
I eventually got him to understand that I (and others) see shouting as abuse. He preferred to call it 'being animated'. I told him clearly that it triggered childhood abuse memories for me (shouting in my face is part of what a brother used to do to me) and that I was NOT going to live with someone ever again who would treat me this way, even if it was only my perception that it was happening. He understood but said that I had never actually told him the detail of the abuse, so am considering telling him a bit more, although am reluctant because it is so painful. I told him that maybe I would be better talking to a trained counsellor rather than my H, but he said that he genuinely wanted to help. He is cross that he has had to take part in family occasions with the people who abused me (before he knew about the abuse).
I know now that I really need to get help to sort out my head before I can start living my life with any kind of normality and especially for my DCs sake so that I can be a better parent. Also to know whether i am over-reacting to anything that DH says or does as I think my perceptions are so skewed.
I have told him that I had considered the end of our marriage and that whatever has gone on in the last couple of days is very serious. I am going to be on my guard now for a bit and see what happens.
We need to communicate much better. I can only hope that this is the start of a better path. Thank you to everyone, I would have been in a complete mess if I hadn't had your very wise input. I have a lot of reading to do from the links on here and to decide if I go to my GP and spill the beans to get counselling, I think I am probably ready as I am so exhausted with keeping it all in my head and having no means of getting it all out.
