<human>: Can you give me the gist of the text in a nutshell?

I've been dating my boyfriend for almost a year. I'm a 19 female while he is 21. I'm kind of concerned with some of his behaviors. He has many reddit accounts and some of them I come by accidentally because he uses the same names for email and other accounts. 

On one of the accounts, he goes on the subreddit r4r a lot. He says he's looking only for friendship but then adds something to the effect of "online fun." I'm not sure how to take this. In addition, on this account, one of his comments was that he didn't have a girlfriend. What should I do? I know that many of the answers will be "break up with him," but is there any way to resolve this without going there? He's a very private person so I don't want to tell him that I know about his reddit account.
<bot>: Boyfriend has multiple reddit accounts and posts on r4r looking for some "online fun" and has said that he doesn't have a girlfriend. Any way to address this without breaking up?
