UPDATE.
Last night I came home from work and he was being off with me. I just watched the traitors and went to bed. He came to bed at 3am after gaming all night.
I intended on taking the DC to my mums tonight to see her and then would call him from there as you guys all advised. Slightly complicated by my youngest being really unwell (flu/temp) and my mum being pretty old and unwell herself.
He woke up at 11.30am, came downstairs to me and the kids (I had been up all night with the youngest and then up at 6.30am) and startted telling me about something on the news & how tired he was! DC started talking over him & saying "mum mum"
He says "I don't know why I bother" and leaves the room
Comes down 10 mins later and put on the most wild display. Crying, screaming "you are so cruel Ginge. You think you're strong but you're cold and cruel. I'm telling you i feel igored, unloved". I just keep saying "please stop the kids are right here" and walking to other rooms and he just keeps going with this shouty crying display "i'm not arguing, i'm not fighting, i'm desparate, why don't you love me, you're the cruelest woman i've ever know. look at your sitting all sterm and unfeeling" (I was just trying to be calm and manage him). he was doing some crazy breathing thing. it felt like such a show to me.
I didnt' really say anything other than keep asking him to stop in front of kids and him saying "all you care about is how DC feel about things, but i'm your husband and you don't care. you're so cruel"
This wentt on for about 25 mins. He then gave up and packed a small bag and had left.
I really really don't want to go to my mums. not least because she is unsupportive and my kids don't want to go either and we are now home wiout him. i feel a bit shell shocked. pleased he's out the house for now.
i don't understand how he doesn't see how bad that is for the DC? he kept saying "it's not me that is causing this - it's you" as i'm just sat there. he thinks i'm cold and cruel but i'm staying calm for kids.
god. that was awful. playing with DC now and then just said "daddy seemed sad" but now we are playing and wtaching cartoons.
