Ok, so here's the deal; I'm in college and have a girlfriend at another college who every guy there drools over. Fortunately, she says that she loves me, and her actions prove it. However, there is a particular guy who comes onto her pretty strongly when I'm not around, leaves messages on the board outside her room that are overtly mushy. Should I ignore this dude, or say something to get him to back off? Whatever I do, I don't want to be immmature. Any ideas?
