Advice??

So me and my boyfriend have been together for almost 3 weeks and I asked him about having “single” still in his bio on Facebook and he said it’s just cause he don’t get on Facebook much and that he only gets on there to talk to me. But see I asked him about it and it’s still on there its starting to bother me. Should I ask him to take it off or leave it alone? Like seriously what’s a girl gonna think when they get on his profile and see “single” and scroll down and see pictures of me and him. They’re gonna be like oh he must not care about her that much I’m gonna go hop in his inbox. Sorry for the long post it just pisses me off.
