Can't edit. I guess I'm just trying to say that he might be feeling nothing but positive feelings and just wisely making sure he doesn't rush things, particularly with his kid. He told you as much. None of that necessarily means fear or negative emotions. It could even be the opposite, he feels like running away and getting married so is trying to keep himself from losing control out of love for you.
Keep calm and do what comes next!
