Things have not been good between me and DH since I became pregnant with DS1. His behaviour changed to him being extremely possessive and controlling, and he has physically prevented me from leaving the house, etc. on several occasions. I suffered PND after DS1 and DH used this as an excuse to belittle me and my parental abilities, running me down and talking my friends and family down until I had no one left in my life. He manipulated me into having DS2 by promising he would change but if anything, he got worse. I was very poorly after having DS2 and he never helped me. His aggression got worse, falling out with neighbours, friends, getting into arguments with people wherever he went, and being increasingly confrontational with me, and shouty with our boys. I'd finally had enough and was making plans to leave when DS1 was diagnosed with leukaemia. His treatment will take three years. DH is devastated, but has so far all but abandoned me to look after DS1 in hospital because he 'can't cope'. AIBU to put off my plans to leave until treatment has finished? I don't want to be alone through all this, but also don't know if I can cope with DH's behaviour any longer - especially right now...
