I'm in a relationship that has run its course. I'm sure of it — we've been distant, we haven't been communicating, and I'm happier when I'm with other friends. However, I really, truly care about my boyfriend. I don't want to lose him as a friend, but I won't be able to keep him in my life. In my experience, I can't be friends with people I've dated. It's just too hard and I'm too emotional about it. I've had relationships that ended before, but I'm really struggling with this one. I feel like I'm breaking my own heart, but we aren't putting in the effort here, so things are just falling apart. How can I muster the courage to break it off?
