Thats a good one!..Love is a feeling...a emotion...just like hate,anger, saddness, happy, and i would think that if u can feel those emtions then how can u not feel love ?... There are people who can not feel pain, but that comes from the nerve system,, this is totaly different wouldnt u say.. So I would look at the person telling u this...if they have all the other emtions then its a safe bet that they can also feel love...it might be a way out of dealing with stuff they dont want to..
Good Luck! peace out..
