Love is a very contradictory word. It can mean many things, depending on how you look at it. Of course, I don't love my boyfriend the way I love my dog, but I do feel affection towards both of them. To me, love is when you have feelings for something or someone that you just can't describe. It is a wonderful thing.
Hope this helped!!! :)
