<human>: Aghhhh, I've (21F) been dating my boyfriend (22M) for two years now but we're just getting through a rough stage in our relationship so things are still a little hairy. 

I might be going back home over Summer while he stays at the town we both live at for university. The only thing is he's going to be there with a girl who I know has a mega crush on him and he doesn't mind the flirting as he is rather flirtatious by nature. 

What can I do to quell my fears? I don't want to be away from him for three months! I may sound very ridiculous and over the top, but I have knots in my stomach..

Provide a brief overview of the text.
<bot>: Moving home for a few months, leaving boyfriend with girl who is crushing hard on him. How do I handle this without feeling miserable?
