What does "love" mean to me

It's very hard to answer this question!
But I think it means care about others with no reason or no reward. I thought just keeping the relationship could be love. Imagining the married coulple having no talk, however, its not. should be more positive.

So I say it is care for others.
What I mean by caring about others is love starts just with care in one's mind even though it's not expressed out.
And I think it's a process like you care for others in your mind and expess it, and then it becomes love if they accept it. If they don't, that's not love.
Moreover, if you take care of someone for your benefits, that's not love.

This is my opinion. But I'm still looking for the answer.
