Thank you for all of the responses. This is very helpful and food for thought.
SeveredEd I do feel like my feelings have gone off like a switch, both emotionally and physically - right now don't feel like I could ever be with him again physically and there is no love left there. When I think about him, I just think about all the awful things he has done and said. Also feel like I have lost the trust and might forever be suspicious and worried that he might become abusive again.
MrsJREwing that is very interesting, DH also snores, but also does have MH issues - suffers from OCD for example - and this time around the few times I managed to get health professionals to see him or discussed his behaviour with them they did diagnose mental illness. But does mental illness drive a man to be abusive or does it have to be in him already...
Unfortunately DH has refused to seek medical treatment until now, refused to have any medical tests (blood or other) to see if there is a physical cause, refused to take any medication (including anti-psychotic drugs) that was prescribed him. And even now via our lawyers has offered to go to marriage counselling with me and now to jointly go to see a psychiatrist who specialises in marital/relationship issues - but only if I come with him. So I think he still doesn't get it.
DH never precisely hit me (no black eyes) but possibly worse - he has pushed me, grabbed me by arms and shaken me, kicked me in the shins while in bed, deliberately woken me at multiple times in the night and kept me awake by things like yanking pillow from under my head (every night), hitting me with pillow repeatedly, poking me in ribs or back, groping and harrassing me physically, episodes of trying to push me out of my bed, very extreme verbal abuse (every single day for hours on end), shouting at me, physically threatening me (shaking fist etc.), trying to physically overpower me to get hold of my mobile phone on one occasion -- and all this in front of the children. Oh, and all of this went on for nearly 4 months. So not just physical but emotional and verbal too.
cestlavielife he has displayed controlling behaviour previously, mainly since DC were on the way or came along, and that is what I am worried about - I had always taken them as rare one-offs that I put down to stress or something - but now thinking maybe they weren't (although there was never, ever any physical violence until some 3.5 months ago). And he had started to isolate himself - and us - both socially and from family starting some 3 years ago (around when first DC was born), so well before the horrendous events of last few months.
And I am seeing no signs of him accepting that what he did was wrong and that he needs to do tremendous amount of work if he values his family and children. I think he still thinks this is a "marital spat" and I just did this to play hardball with him.
Reading back all that I have just written it doesn't sound very hopeful does it?
