Will it still work??

So my newly boyfriend is leaving maybe for the whole summer but I'm really hoping it will still be normal. He's only gone for 2 months so it won't be that bad but I'm still scared that we are gonna miss him a lot but I don't wanna break up. What should I do?? Just make sure to ft him and text? I truly trust that he's not gonna go off and meet other girls and I won't be with other boys.. just wondering what to do??
