your crush loves you! he seems to be attracted to you, and if he knew you liked him, he would probably ask u out! so you should go ask him out when you get a chance.
You like having someone to call your own, someone to make you feel loved and appreciated. You have an emptiness inside you that is constantly being filled with with the occasional "i love you" from guys who just want to get in your pants. Don't be dependent on a guy to make you happy, learn to be comfortable with being alone and the right person will just fall into place.
