<human>: Female/17/ duration of relationship - 8 months 

I don't want to say anything to him because I dont want to insinuate that I'm anticipating him cheating or for it to insinuate that I want us to break up, but my boyfriend is going to uni in October (he has an unconditional so he definitely IS going - yes it's 6 months away but I can't keep it concealed much longer) and I'm absolutely petrified of falling too deep in love and getting seriously hurt at our break up. 

I can't decide whether it's best for me to break up with him NOW rather than leave it for our relationship to develop and me get into things too much...

I am an uber emotional person and I just don't think I can deal with the idea of him being away at uni...his course is 3 years long, too.

 I don't want to hold him back, either! I guess I just want what's best for both of us.

 But my friend's parents have been together since they were young and her dad was in uni for like 6 years and they're happily married. I know it seems a little bit cynical but I can't imagine that being the case in 'our generation'. I keep going over and over things in my head and I just can't bear to think of losing him, not now, not when he's at uni...

it's so confusing and stupid and I just feel like an idiot. I know that if I mention it to him he'll be absolutely brilliant and be all 'don't be so silly' etc but I can't disregard the nagging doubt in the back of my mind that I'm perhaps being a little naïve. 

I honestly do love him so much and I think that's why it hurts so much...I've even considered 'putting myself off' him (which failed miserably)... I just can't and don't want to have to get my head around it all.

Summarize the given text in a few sentences.
<bot>: He's off to uni, and I'm super insecure about losing him but I don't want to voice my concerns to him because I'll just sound bare stupid
