I'll take the correction, if and when we do fall under the common-law marriage clause we will be legally classified as married, and as per our agreement, she will have claim to the housing situation, this is known and accepted. The difference is that she isn't with me for my house, and contrary to innocentman's jealous rant, her paying me "rent" is established because she still needs to pay for housing somehow, nothing is free. If she decides to go batshit crazy, then she will and shit will fly no matter how bullet proof the agreement is.
My entire financial life went into my housing investment, so taking at least some precautions to protect it were necessary, and anyone who believes it to be stupid obviously haven't been in a situation where a huge portion of your financial assets are on the line.
Innocentman, get off the internet and get a real job, buy a house, get some responsibility, and you'll figure out how life works. If you'd like I can find a nice pastor to marry you and your boyfriend so that you don't have to be in this situation

As for calling her a skanky unemployed bitch, I'll bet you she makes more money than you do
