The correct answer is paradox.
Paradox is a figure of speech that combines two completely opposite things into one. In the excerpt above, we can see that the speaker is willing to wait for his/her loved one his/her entire life, however, only if they don't take too long to get to him/her. This is a paradox because they weren't willing to wait for them long in the first place, as it turns out.
