well, i would say yes, you can "love" someone, but not be "in" love with someone.
the first thing that came to mind for me would be the relationship between a parent and child. Now, a parent "loves" their child - but they are not "in" love with their child.
I think as well its possible to "not like" someone, yet still "love" them. For example with me and my sister.
To be honest - I hate her. I cant stand to be near her. I hate the way she turns everything into an arugment, i simply do not like her personality at all. I dont like her end of. But...i still "love" her in the idea that she is my sister, shes part of my family, i would hate and be devestated if anything bad ever happened to her. so i dont like her, but i still love her.
