Have you ever been to California?
Sign "you," then "ever" using the single loop and downward motion, followed by "touch" (the ASL concept for visiting a place) and "California." Remember to raise your eyebrows since this is a yes/no question.

I will love you forever.
To express "forever," you can use the sign for "ever" with a slightly larger, more exaggerated movement to emphasize eternity. Sign "I," "love," "you," and finish with a strong, sweeping "ever."

Nothing ever changes around here.
Sign "nothing," then "ever," and finally "change." Emphasize the sharp downward motion at the end of "ever" to convey a sense of certainty or frustration about the situation.
