hope that helps you :)
Love is a human emotion (domesticated animals usually as well). When I think of love, I think of always having my mind on that person, wanting to be with them, and picturing yourself with them in the future. Then there is lust, when you are sexually attractted to a person at a given moment, usually when you are near them. Also, I am a male, so my views may be different from a female's, but love should be the same thing. Sometimes you might love somebody, but they don't love you, or they don't know they love you. It can be very complecated. I am currently in a situation where love somebody, but I don't think they love me.
Some people use suduction tactics, such as soul-gazing, which can lead you to believe you love them. If you first started thinking you loved someone after a suduction tactic, you might actually not. Once again, love is coomplicated, and it's up to you to figure out if you love someone or not.
