GUYS!! Should I be worried?

My boyfriend said "brb" tonight on skype two hours ago.... and he has yet to come back. He is really sweet and he always makes me feel comfortable. He does cute little things to make me happy, and he told me he loves me yesterday. I met part of his family today, and I would say it went very well.(: But he has not returned to skype yet, and it is kind of making me a little nervous. Do you think he just got caught up in something, or did I do something wrong? What should I do now? Thanks for the advice!! <3
