i just got told that love is impossible...

okay so my bf just told me that love is an impossibe emotion and that you cant feel it. and that he has no clue what he feels about me. by saying that he pretty much broke my heart into a million peices. we're not broken up... yet but by the sounds of what he said it pretty much sounds like he wanted to end it.. i have no idea why... i haven't done anything wrong and i love him with all my heart. i mean i just don't get how he can say that love is impossible. he was the one who said i love you first and who says i love you back everytime i say it to him. if it's so impossible to love than how come he was able to say it then?
