I've come here for comments or advice because I can't think of who else to turn to.
I'm male, married 19 years with 2 DS aged 15 and 18. Our marriage hasn't been easy at times but we've stayed together for the children. There aren't many arguments, but no intimacy either. We still holiday as a family, eat together etc.
For all the time we've been together my DW has had occasional rages. Usually they are triggered by something small - utensils moved out of place in the kitchen or an untidy room but they can last for more than an hour. During that time doors are slammed (to the point of plaster coming off the walls) and me and the children have abuse screamed at us ('You stupid fucking shit', 'You're a fucking liar' 'I hate you all'). There is sometimes violence; very rarely against me, but I have had to physically step in a few times to stop her lashing out at the children, and she's put holes in the wall. My guess is that there are mental health issues and I know she has seen a doctor but she refuses to discuss it. In between these episodes we can go for several weeks with just occasional raised voices, and she will take the children out for treats as normal and make sure they are properly fed and clothed.
Last week I came home late from work to find that there had been a row about an untidy room. DS2 was hiding under the bed, sobbing while DW was screaming 'You shit' and putting rubbish in the bin. I persuaded her to leave after DS2 started hyperventilating. Later he explained that he had been asked to tidy the room but didn't. She started shouting at him so he locked himself in but she had started to force the door so he opened it. When she came in she hit him more than once. He said that it had got the point now where if he hears a teacher raise their voice at school it brings flashbacks and he wants to cry again.
I know I should leave for the sake of the children (the oldest will start uni in September) but can't see a way out. The house is in both names although I pay the mortgage and all bills. I know that DS2 would hate to leave here, although after the last episode he threatened to run away. We both work in this area and don't have family locally. MiL is wonderful and a loving grandparent, but she has been on the receiving end of a similar situation herself.
How do I know if separation is what the children want? I don't want to go behind DW's back, but don't want to risk triggering the mother of all rows if I try to discuss it with her. If we do split I have no wish to go public about the reasons, and hope we can still be friends. I couldn't risk her getting custody of DS2 though.
It sometimes feels that we've spent so long treading on eggshells that this is normal; it's only times when she is not there that remind us what it is like not to be in fear.
