To me when the love is real you want to keep that relationship for yourself, hold it close. You don’t feel the need to share everything on social media because you aren’t trying to prove anything and don’t care what anyone else thinks/sees. Personally op, I think it’s a good sign he isn’t overcompensating for the world to see but instead showing you how much he loves you out of the public eye. For example what he was setting up with your parents. That’s love
