Boyfriend issues ?

Me & my boyfriend recently had a falling out. He broke up with me took a girl on two dates... We decided to work on things & since then we have been great.... except for one thing. He won’t put that he’s in a relationship on Facebook or let me tag him in anything bc when I do it doesn’t show up on his profile just mine. He gets mad at me for bringing it up by it really bothers me.. he says it has nothing to do with another girl just that he doesn’t want a relationship that’s all over Facebook ? But all I’m asking is for him to acknowledge that he’s in one on Facebook instead of everyone thinking he’s single which he was fine doing before & now I feel like he just doesn’t want anyone to know he’s in a relationship. What do I do???
