Amy and Chris are not married as of yet. It took this maybe confirmed bachelor three years to put an engagement ring on it. I'm getting there never will be a wedding.
Realtors , as far as I know, don't have pension plans, insurance and 401k's. They are outside contractors working on their own for a real estate company.
With that said Amy and this reality show have to be a dream come true for Chris.
Chris might get comfortable with Amy taking care of him. Who knows? He seems like a pretty nice guy who doesn't 'poke the bear'! Maybe the two of them will find a nice companionship with each other.
Re Amy' S appearance I don't think she understand the importance of being TV ready. Her hair, teeth, nails all need work. She would never be a beauty but I think she would be more presentable. I don't think Amy likes spending money.
