How early in a relationship can you ask if the other person is dating other people? It can be an honest and nagging feeling we can’t control, but it can have disappointing consequences if not handled properly. Brooke has how to deal.

Dear Brooke, 
I’ve been doing the internet dating thing a little bit, and I’m surprised by how well it seems to be working. I’ve been talking and hanging out with this girl a little while now and really like her. But based on her tweets and Facebook statuses, I think she might be going on dates with other guys too. I’m into her, point blank—and I feel like a teenage girl saying this, but I really want to know: Is it a little early to say something about dating other people? And more-so, at what point do I have a right to be jealous?
