5 years together, engaged for 3 years. Help me?

Maybe I'm being insecure but this has been bothering me. I haven't asked him yet. So recently I posted a picture of me and him on Facebook. The picture was on his timeline for about a month. Recently I've got a notification that re untagged himself from the pic and hid it from his timeline. Not only that. I also noticed he changed his relationship privacy from only friends can view to only close friends. He is a public speaking, a coach and he travels quite frequently. guys please help me. Am I being insecure or too sensitive about it?
