<human>: Can you provide a brief rundown of the text in within 3 sentences?

I dated this guy for a few months after having been in the same friend circle for a few years. He was wonderful and we ended up really liking each other but unfortunately, I ended up getting into law school several hours away (Michigan, he's in DC). We didn't want to do long distance, so we "broke up" only we still see each other occasionally when I'm in town on breaks and hook up. 

I basically need some help in dealing with this situation. Sometimes I feel like things are fine and it's kind of an at-will hook-up which is convenient and nice when it happens, but at the same time, I have had trouble moving on and dating other guys (not to mention zero time, because, guys law school is hard) and the thought of him with another girl makes my skin crawl, though I'm sure it's happened at least once. 

I don't want to lose him in my life and daydream about us getting together after I finish school but I recognize this isn't healthy (and it even sometimes interferes with my schoolwork). I think I know the answer here is to cut him off completely, but want some encouragement or advice on other ways I can keep him in my life and stay in touch, but not let it be a detriment to my day-to-day life. i want to be open to meeting someone here too if possible. If you've had experience in this kind of situation (the dreaded wrong timing issue) please share your experience. I am not consciously waiting around for him (going on dates, trying to meet people, not reaching out to him when I'm here at school) yet I may be holding myself back by continuing to see him every few months.
<bot>: Broke up with a wonderful man to go to school, we still hook up but it's making me a bit nutso, trying to figure out if this can continue in some fashion or if I need to cut him off completely.
