My boyfriend hasn't come back yet?

My boyfriend said "brb" on skype an hour and a half ago, and he hasn't come back yet. He is the sweetest guy ever. He does things for me all the time and always makes sure I am comfortable. He told me he loves me yesterday. It's a long distance relationship (we met on vacation) and I met his brother today. It went really well. So should I be worried that he hasn't come back yet? Thank you in advance! You all are awesome.(:
