Its so cruel when people lead others on and then just drop them!

Hi, hello. So I have this friend who has a boyfriend that is head over heels for her and my guess is that as soon as she graduates he will propose. He is one of the sweetest guys that I have ever met and I find really disappointing to think that she maybe doesn't return those feelings. He is going to get his heart crushed yet and it is too bad. It bothers me when people lead others on especially if they already are seeing someone. Just stop doing it.
