I can identify with your situation too. I have put up with horrible verbal abuse from a stepson and sometimes from my husband as well. I applaud the fact that you were able to set a boundary. I find that really hard but necessary sometimes if you are going to maintain any self respect at all. I have to keep telling myself no one deserves to be verbally abused and degraded regardless of how angry one might become. You sound like a compassionate person who is learning to take care of herself. I am impressed that you have been able to stick to your boundary. Hopefully it will give him time to cool down and behave rationally
