I forgot...how old are you? If you are over 21, your dad needs a little pat on the head when he acts like that. A kiss on the cheek and a smile. Cute but no longer appropriate reactions, even for a parent.
You are mistaking your friend's reactions for demands. They are reacting but have no right to demand from you. You don't need anyone's permission or prejudgement and if your friends demand that from you, it's coming from THEIR ego, not any wrongdoing on your part. They should be supportive no matter what period along the timeline of a project you decide to confide in them. They need a little pat and a smile too.
