Boyfriend is on Facebook but won't text me all day?

Anonymous
So my boyfriend will send maybe 2 messeges to me in the morning but then he womt asnwer from like 11AM until the next day! He doesn't reply to my texts for over 13 hours! Then I'll look on Facebook and it says he was active less than 20 min ago. Would guys still talk to girls if they have me in their profile picture? Or would he talk to girls (his ex) anyways? He has girls as his friends but they will only have him as a friend! Is he talking to girls on Facebook at all? Why won't he text me back? Please help, this is driving me crazy.
