Rabbits and Wolves

I was talking to a friend last night and somehow we got on the subject of my love life (or lack thereof), and he gave me some advice. He told me not to tell Jeff (the guy I'm in love with) how I feel about him. When I asked him why he basically told me that the probability of me getting heart broken was greater than the probability of him having feelings for me. Well, needless to say, I didn't like that answer. Then he gave an interesting, but good, analogy. He said to me, "You're the rabbit, and he's the wolf." I didn't like that either, but I saw what he was trying to say. My question is though: Are the people who are in love really the rabbits, and the ones they're in love with the wolves? Do our 'objects of affection' really have that much power (or potential power) over us?
