Breaking up...

So... Its sad... My boyfriend is avoiding me... doesn't answer my calls or texts.... and whenever he does respond he says "I'm Busy Ill text you later"... I don't know what to do... Cause I'v Fallen so hard for this guy.... He says he loves me.. and that he wants me.... but the way he's been acting it doesn't seem like it... and then the other night he asked me outta the blue "Would you tell my secrets if we broke up?" and of course I said no.... but I think he is going to break up with me.... and it will be awkward because we are also really old friends, we'v known each other since we we're little..... I don't know what to do.. and everytime I ask him Whats wrong he says nothing.... GAAAAH...... What should I do? I feel stupid.... Blah.... Maybe it would be good if we did breakup since Im going into the Marines but... still... I love him...
