OK, now posting in this thread -
Unfortunately I have known a few people who have been in abusive relationships, and quite often they blame themselves. "It was my fault, I got drunk/stayed out too late/didn't empty the garbage." They deny it's a big deal. They want to change the subject. You are now doing all these things, which unfortunately means you are following the same pattern.
And in this case it's not just you - you have your children to think about. Again, step away from the keyboard. Stop posting the silly physics bullshit and get the help you and your family need.
