Why do guys "date" women they find "cute" but not pretty enough for something long term?

I've noticed this. Men have 3 categories:

1. Fuck material
2. Date material (+ sex)
3. Long-term material (when she's very good looking)

Why date someone if you know from the get-go that you don't find them attractive enough for something long term?
