There is a long and complex back story and I have posted before, but in a nutshell I'm in a very unhappy marriage and don't know how to end it. I have 3 children from previous marriage who are in their teens and my husband (their step dad) treats them in an awful way. It's basically emotional abuse, nothing physical but daily criticism, shouting, losing temper and nit picking over the smallest things. They are really unhappy at home and I worry about the long term effects of this on their mental health. This has been getting worse for a couple of years but in the last year has been really bad. I've tried talking to him about it SO many times but nothing changes and we're way past that now - I don't want him here anymore because of how he treats them. He thinks he is doing nothing wrong apart from occasionally admitting that maybe he lost his temper but blames it on their behaviour (which is very standard teen behaviour made worse because of how he is with them). Anyway, I've asked him to leave and basically he is refusing. I've brought it up several times and get "oh this again" or "you can't cope without me" sort of responses. The situation is made more complicated by the fact we had a baby together a year ago so he is using her as his reason for not leaving (one time he said he wouldn't leave unless he takes her with him). We own our house together but I own a bigger share. What can I do? Should I seek legal advice?
