Am I being weird

Me and this guy have been dating about three weeks. He doesn't have a Facebook or really any social media, but his friends do. And a good amount of his friends are girls. He has really no way of making it known that he's in a relationship. So I decided to make us a joined account and send his female friends friend requests, just so they would know that we are dating. He called me because one of friends sent him a screenshot of the profile I made for us saying isn't it a bit too soon to be doing that. He asked why I made them a joined account and I told him so everyone can know we are together and we can see each other messages because we can just use the account to message people. He just said "Thats kind of weird " and hasn't talked to me for three hours. Was I being weird?
