Guys,he's not picking up the phone,what to do?

[PriscillaD]

Since I can only meet my bf in June,which is still months away since I have to attend some kind of camp,I call and text him everyday.Everything went well but since a week ago he won't pick up my call and won't even go online. I don't know what really happen to us.he's always been very happy while talk to me and from the way he say it,I can feel he really do love me.He even said he willy marry me after his army duty finished.But why now he doesn't pick up the phone?What are possible reasons?He's not in the army yet
