Loving

I wonder if people make themselves love. There is such a thing as falling in love, but once you are detached for such an amount of time you feel that need for someone. That's why people date when they are not really looking for a serious placement. People need to feel that.
What about when they don't deserve it? Do people really deserve to fall in love, to be loved? Technically they don't. So what happens if you do? What happens if you dont? How do you know? If you think you love someone but then they don't love you? How does love even start?
I can't even get to the liking part. haha
