Anyone else extremely clingy to their SO? I didn't notice until tonight, its my first night without him since before we started dating. (he was a roommate and best friend for a while, and he only was not at the house one night) I feel kinda dumb for feeling so lost. Not to mention I'll be gone until Monday.
