I can't get over the fact that he won't be with me on facebook?

I know it's petty and unimportant, but I feel like he's hiding the fact that he's with me by not putting it up on facebook. He's a DJ and his facebook is his DJ name so I understand, but it still irritates me and makes me feel like I'm not important. We used to be together on facebook but we broke up and took it off, but now that we're back together he doesn't want to put it up again. He said when we were officially together on fb he got really jealous of every guy who talked to me on there, but he's not jealous anymore. The whole root of our problems is from his jealousy. What do I do?
