<human>: Provide a brief overview of the text.

Background: I'm a 21F with a 21M of 3 years.  We go to the same college, different courses of study and very different interests.

I struggle with clinginess, always have.  I have demanding classes, homework and I make time for that, but in terms of other activities I always drop them to spend time with my boyfriend.  He's my best friend.  I have one club I attend and a part time job during the day, but in the evenings if I'm not studying I'm sitting on his couch.  I like to see him every day, but I realize that's a lot for two busy college students.

He does chafe a bit at the clinginess so I'm trying to change that.  I'm wondering if saying no to his invitations to hang out will make me seem more appealing?  I don't know what I'd do in the spare time, make up something I guess, but I feel like we're always together and I feel pretty dependent.
<bot>: Sorry if this is kinda confusing.  Basically, is it wrong to play hard to get while in a relationship, or can it make attraction stronger (absence makes the heart grow fonder kind of thing)?
