Not sure if I should go....

Tegan
So I recently started talking to my ex but he is now a good friend. We haven't been together since 2013 if not longer. He moved to QLD and has a child and is not with the mother. He asked me the other night to go and visit him in QLD. It's an 10hr drive from where I am. I would love to go to QLD for a holiday and see him. He has never hurt me and been mean towards me. My heart is telling me to go but my head is telling not to go. 
Which one should I listen to?
