I don’t think that without love life would have no meaning, but it is hard to imagine a life without love, since it is something humans are so focused on. There are many people who don’t marry, who don’t live their lives with that special someone.
Personally, I think life is about finding what fulfills you, what makes you happy. For lots of people, love is something that fulfills, and so it is a priority to find “the one.” Others (me included), find contentment in any kind of friendship, and that feeling of closeness with another.
