<human>: Provide a brief overview of the text.

I'm a 17 y/o girl dating a 19 y/o guy. I sometimes spend weeks with him either at my house or his. 
He left earlier tonight after spending a week at my place (including our 6-month anniversary). 
He's gone now. he's back at his place and i probably won't see him for a month. (That's what usually happens) 
We always plan before a month but it never works out. he works a job he hates and has to drive 1 1/2 to school for a major he hates (he's switching now but that's beside the point) He's doesn't like working mainly because he's doing it just for gas and rent to his sister. 
It makes it so he's un-motivated to work. But anyway, We're planning on seeing each other the second Thursday of September. 
But i'm scared it won't work out. and that we won't be able to see each other.
i feel like i'm being overly attached because all of my relationships before him have been online and you don't miss somebody that you never get to touch or cuddle with or just do things with in general. 
but because of that me missing him like a little bitch makes me feel like i'm to clingy even though he's said i'm not quite a few times. i'm having trouble coping with being without him. 
i'm scared of trying to fall asleep tonight because the first 2 or 3 nights sleeping without him i cry. i hate crying. especially for something like this. 
i should be fine with seeing each other once a month for a week. and being able to sleep next to him and cuddle him at all right?
 i shouldn't get upset when he has to leave. should i? 
i don't know what to do. this is honestly the first GOOD relationship i have EVER been in with a guy who actually cares about me, and wants whats best for me. I have no clue what to do.
<bot>: I have been in a relationship for 6 months and i get upset when i don't get to see him for a month, and i feel super clingy even though he says im not
