Yes, there is. Sometimes there's no clear difference. You'll only know when it ends, you're hurt but still you want him/her back. That's love, dude. Because TRUE love is that that overwhelms you and takes you over and you don't really care whether the person loves you back or not. It's only important that you make them feel loved. Like on the other hand is the crazy, happy stage before love. There's no commitment, no relationship, almost no feelings involved yet. Sometimes you just like a person for a certain quality or part of their physical appearance and love means accepting their whole being - flaws and all.
