I was actually getting to know a guy who asked me this question. I told him the truth. I am ready to be married and build a family. At this age and time in my life, I'm not willing to waste years with someone who isn't financially stable and doesn't even know what he wants to do with his life.
He was in his late 30s with an unstable job, still lived with family, and stated a few times that he wasn't anywhere near being ready to afford a family. Well I am, so what was the point of pursuing me? Idiot.
