I miss my boyfriend !

Does anyone ever miss their boyfriend when they go away for vacation ? like I'm 16 and so is my boyfriend and I've had 1 previous serious relationship and I just didn't have the same feelings that I have for my current boyfriend ! like my boyfriend is on vacation right now and he's going to be gone for a week! I really miss him , like I'm sitting here crying . I've never cried over a boy like this before !! Even when my ex and I broke up I didn't cry until a couple months later . like I know my current boyfriend and I have had sex .. Like I honestly feel like I'm in love with him ! What does it sound like to you guys ? Am I in love or am I just in a phase ?
