One thing to be careful about is being viewed as a parent by the child. Yes he may have a dad, but the child may also begin to associate with you. My friend's relationship that ended after a year to two years (I forget how long) ended up causing the child to begin to act out and doing poorly in school, like the kid was experiencing two parents divorcing. He helped take care of her (she's about 7) and even took her to school most days when the mom worked in the morning.
