If you never disagree with the person you love, something is terribly wrong. Some people are afraid to be themselves with another person. Such fear negates love. The Bible says that perfect love drives out fear (1 John 4:18). You can't really love someone with whom you can't be separate. That is, love does not mean losing yourself but rather frees you and empowers you to be yourself.
