Is it normal that i like watching romance but i never partake in love

I have always felt separated from other people.At first i thought that i was in some sort of phase but then ,even when people told me that i was isolating myself i thought they were joking but then my friend told me i watch to much romantic movies and that i should go find a boyfriend.And i listened but then well lets put it this way he was sort of not what i expected.And when we broke up i was in lot of pain but i recovered in 3 days.After that i felt that i gained more experience but it was more like a information and less like emotion.I felt empty inside like i always feel but that happy mood was out of the picture.Never have i felt so isolated and i thought to myself what is a point of being with a person if he is going to betray you and stomp on what is left of you.At least in my fantasy world real love is something pure and eternal but in reality what is love!Is it just a feeling that can drift away anytime or am i someone who just cant understand human beings.If so then what should i do to stay true to myself and not chose the wrong path.Should i listen to my heart or my brain...Is my life going to revolve around watching other people and their love life and i should get nothing this world gives to me .Like real emotion or real feelings!Not just my imagination but people who will like me for who i am!Or am i just losing my mind here....
