Confused.

I am new in the dating scene and I am seeing a guy I like now for five months. Both of us don't want a relationship right now because of school and work going on. The thing that I'm confused about is the stories I read in this app. A lot of questions about - having a problem with a boyfriend telling him they love him/in love with him.

So the real question is: Why do people decide to be in a relationship if they don't love each other?
