I Don't get it

I just don't get it. If you want to be with someone like what is the big fucking deal. If you feel a connection and sparks everytime you kiss that person then why arent you together. I don't get it. You have the same conversation every single day about how much u like each other and have these felings but when it comes to getting a in a relationship everyone puts on a dunce hat. I can understand fear and understand dissapointment. But we are getting to the point that we are to old to be afraid of little things like that messing up in our lives. You will never know anything in this lifetime unless you try. Man I just don't fucking get it.
