<human>: I'll make this as brief as possible!

My boyfriend and I were roommates before we started dating. We lived together for about a month before getting together. Obviously this is kind of an odd situation, but for the duration of our relationship it's never caused any problems. In fact, it ended up being an advantage because our clashing schedules only allowed us to see each other late at night during the school year. Living with him was fun and we've only had one fight during the whole year, which I think is pretty good. 

The problem is that the lease on our apartment ended on the first of August, and we both moved in to separate apartments with separate friends. We now live maybe a mile and a half away from each other. At first I thought not living together would be a good thing, but lately I'm just really depressed about the whole situation. I miss sleeping with him every night and spending time with him. We both work 30-40 hours a week and go to school, and I'm afraid that when the new semester starts I'll never see him. On top of that, despite my best efforts, my insecurities are getting the best of me and if I go a few days without seeing him I automatically jump to the conclusion that he doesn't want me anymore and doesn't care about me.  I feel like I'm losing my mind and I'm considering breaking up with him because of it. I don't want to turn into a clingy obsessive girlfriend. He doesn't need that and neither do I. 

Normally I wouldn't worry about this too much and kind of let it play out for awhile to see what happens but I can't go through a day without crying and worrying over it, and it's having a major effect on my everyday life. Has anyone else been in a similar situation? I'm at a loss over how to handle this.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Boyfriend and I lived together last year, moved into different apartments recently and I feel like I'm going crazy over not seeing him. Not sure if it's best for both of us to just end it or not.
