<human>: Can you condense the text into a few key points?

My boyfriend and I go to the same school and live quite near to each other on campus, so when classes are in session we get to see each other every day. We hang out anywhere from 30 minutes to the whole night, schoolwork/classes/roommates permitting. After a year of dating, we're pretty comfortable with each other, and I enjoy every little moment I get with him, be it going out to dinner or studying side by side. He pays me plenty of attention during these times and I feel loved, secure and happy in our relationship.

However, when we're apart, either from our month-long winter break or  like we were during the summer, he RARELY initiates contact. Admittedly, I'm a little clingy, so this really bothers me. Not that I believe he's wandering off after another girl, but because I just want to talk to him. All I really want is a text a day, which could be as small as "Good Night!" I've talked to him about this but the situation never really improves. 

Am I asking to much? How much contact do you expect from your SO when you're apart?
<bot>: Boyfriend doesn't contact me as much as I'd like while we are (physically) apart. What do?
