A person can feel love, infatuation and lust all at once, to some degree. But if it always her/his body and looks that you end up with, it is a feeling of intense lust.
If two of you argue a lot and then don't make any conscious efforts to patch afterwards, your relationship is merely based upon lust.
You don't like to share your deepest feelings with him/her and avoid talking or meeting with that person until you get horny again, it is not love.
