As vblord and others have said: you need to work on the product if ultimately you want it to grow.

But here's another way you can make some money with 3k users: sell something to them. As some have said, things like custom emojis, digital roses, etc, might work. But think outside of the tech box and offer to sell actual physical things e.g. a user could buy flowers for another user and you take care of the service and take a cut out of it.

There's actually a show right now on tv called "Halt and Catch Fire" (http://www.imdb.com/title/tt2543312/ best show ever about tech imho) and they're trying to grow a startup who's service is a chat service!
