[Handsome Creepy Eel]

Call me Beta, but I'd have no problems covering all the habitation and food costs. I'd sure appreciate it if she wanted to chip in, but I'd never ask her or expect her to do that. My apartment doesn't start costing more just because she moved in, the internet is flat rate, the electricity and water costs increase negligibly, and I make more than enough to cover the food and hygiene (the biggest variable expense) for one extra person. Surely a girl who treats me well, cooks and cleans for me and so on is worth more than that.

If I am not happy with the girl to the point that I am considering ways how to make her "justify her worth", there's no way that she's moving in with me anyway. Age is not a factor in that - only me being happy with her is.
