Does love to human exist in this world? Or just desire that stimulate our feelings...

Does your partner love you so much?? Will he/she sacrifice everything for you?? I reached at a state where I feel that people like or love us for some reasons. For example, I like Britney Spears because she is hot and sexy not because who she really is. Do materials that someone gives you make you love him or her more? That means he or she loves you because of the materials you gave not for who you are. Yes of course, people can say I can like or love anyone I want, that is my right to do so. I have a lot of friends but if I ask one by one, will they like me because who I am or just because I am funny. I like to give jokes, make fun of people, laugh at people, and try to make people around me happy. However, I do not know whether people around me can accept who I am because I cannot read their mind. People can smile but they can hate you so much (reality in life). Same goes to love... Love should be something “nice” in life but love is not concrete like a wall. We cannot see love but people always say we can feel the love; is that love or just desire. Do we need reason to love someone?? God always give us things to wonder in life. Not every question has their specific answer. One thing I know is that the love to God should be beyond everything in our life. Does love to human exist in this world?? Or just desire that stimulate our feelings... I still wonder...
