I've posted about my situation before, long history of EA. I want to leave and I can afford to and we've got no children.
This week it has sort of come to a head, if said I want to leave and he firstly said well pack your kit then. Then he sent me a text messgae saying he wanted to commit suicide, "I've decided to end it all and you can be happy", then today on the phone he said if I left him he would destroy everything, he would burn the house down and destroy all of our assets (I don't even want the assets, he can have everything...) but now I feel like I either get on and be unhappy or I leave and he could do anything.
