My husband needs to get his ass out of here before my homicidal urges get the best of me.
Are you seriously talking about killing your husband? I hope not!
The urges come in waves. How could I not want to do it after he is rude to me?
It is bad to want to harm anyone.  Especially if you are married to the person.  Have you considered divorce?
I have and it's the primary thing that keeps me from going further with these thoughts.
You should absolutely not act on these urges. Killing someone is never the answer to a problem. Filing for divorce is much easier and is what you should do so that you don't end up in prison for murder.
