Then trust me when I say it's not love. You may have been experiencing stronger emotions than you have ever felt for another person, but that does not mean that it is "Love" by definition. To really feel and share and experience true love, the two people (assuming this is a romantic relationship, otherwise, the same essentially applies with certain modifications), the love must be mutual. You should both care about the other in such a way that the other person's happiness is AS or MORE important than your own.
If that is not the case, then who is the person that you supposedly love? Someone who is selfish, unkind to you, abusive emotionally and/or physically, a person you WISH existed but actually does not, an idealization, someone who doesn't even know you exist, someone who toys with your emotions, someone who CANNOT reciprocate your feelings because he/she is completely unaware that you feel the same way...etc., etc.
True love is reciprocal. You may briefly feel that you love someone who is not aware of your feelings, but it has to amount to something REAL to actually be Love in the true sense of the word.
Love, REAL Love is reciprocal. It is a feeling of one-ness, a knowledge that you both need each other is a very profound way, it is trusting another person with your heart and having them put that very same trust in you. It is valueing your life less than the life of your loved one and having that same feeling reciprocated...KNOWING in your heart that this feeling is reciprocated.
Love is rare, but true and real and it exists beyond any doubt. If you have not felt this way, and had someone else feel the same way about you in return, then you have not experienced true love and you have the hope of true love to look forward to.
If you HAVE felt this way and had another truly feel the same way about you (genuinely and for a period of time), then rest assured that Love definitely exists (even with its flaws and possible disappointments) and you have experienced one of (if not THE) greatest things that life has to offer, and that in knowing that this exists, you have the absolute hope of finding this again, for real and for life.
