Can my wife just throw me out if we are married legally going on 6 years?

The answer to your question is No, she cannot just throw you out of your home. Perhaps the better response would be for you to seek employment. That way, you and she would have more spendable income, a happier wife, a more productive life and save your marriage. All of those are good. Good luck.

She can threaten this, but she can actually do it and get a court order removing you from the home if there has been any domestic violence. You need to go see a family attorney immediately.

No, she cannot throw you out of the marital home, even if it is only in her name alone. She would have to either formally evict you or get some other form of court order in order to forcibly remove you from the home.

She has to obtain a court order first. Use of a lawyer is recommended.

Generally, no. The bigger question is though, why you would want to stay with someone that wants to throw you out, especially if you're unemployed. Staying together with a partner in the same residence when that partner wants you out can often become a recipe for bad things - - false allegations of domestic violence against you, actual domestic violence by her against you, the hiding or liquidation of assets, alienation of children (if any). You don't indicate whether you want to stay in your marriage, or go to counseling to try to work things out, or whether you're done, but either way, you should consult with an attorney to educate yourself about your rights and obligations, and to discuss the specifics of your situation and your options.
