Reading the OP's entire message revealed that her boyfiend isn't interested in protecting his interests. He's interested in asserting control. This is a cohabitation contract, not a legally, binding contract of marriage. In most Family Courts, cohabitation issues don't have a whole lot of legal remedies. It's like playing house, and then demanding the legal system to sort things out when the game goes south.
Prenuptial agreements? I have no issues with those. Cohabitation contracts? ROTFLMAO!!!!!!!!!! And, from what the OP described as the "terms," I have to just shake my head, do an epic face-palm, and go get some coffee.
