that is love?

That's not love. I never experience to love a person and get abandoned, maybe the reason of the other people is they are not ready to enter or commit in any relationship by now. So we also need a time to find our true love.

you have not discussed your point clearly. there is a possiblity that you have not yet fallen in love. people have left you because your fels were just of infatuation or attraction. i you feel that it was love then you feel for the people who were not interested in you or they were committed to someone else. if this is also not the case then may be you could not present your feelings to the person properly and thus they never understood you. there is no use thinking of the past or repenting about it. start afresh, look for someone who is comfortable with you and someone who would be happy to spend a life time with you.
