My wife had both physically and mentally abused me for a year or so. Has got worse in the past few months and I have thought of a divorce for the first time. I have never fought back, not in my nature. We own a home, business and have one child together. She blows up and says she will call the cops on my for abuse on her and my child and I will be taken away because of the fact that I am the man. There is drinking and drug abuse in her daily life and I am at wits end. I thought of taping her accusation, verbal assault and made up lies . Is this legal in Washington State. Need to protect myself from her and her exteam anger issues. Afraid that my child will be next and I can't let that happen. One taped conversation with her would guarantee that I would be able to be a Dad.
