yes 'losing it' was wrong. you know this, that's why you're here.
people who have been where you are will understand what happened.
now is the time to be honest with yourself and admit that the relationship you've been in is well and truly dead and buried.
you are being subjected to abuse of the highest magnitude.
this has driven you to react in a way that is not characteristic of you, and not what you want your life to be.
when in extreme circumstances, extreme things happen.
take responsibility for what you have done, but understand that it's symptomatic of the problem not a cause of it.
draw the line. end this torture.
get legal advice pronto, save as much of your situation as possible, get him out of your life and if you have children work night and day to make sure he doesn't let his poison seep all over them.
we're all aCcused of being crazy, abusive and hated by our abusers. they throw at us what hurts THEM the most. seeing you descend to his level has pleased the abuser you're married to.
time to end this and remove the victim(s) from his clutches. you can, and must do this!
