You know I love you, but it's too much. We've been spending too much time together, and I really want to see other parts of my life. I really don't want to hurt you—you've always been there for me, and we've had some great times. Remember this past Saturday, when I kept thinking "It's so nice outside, I should really go for a run in the park, or get a coffee and take a walk on the beach, or I should make one of the million recipes I've saved to Instapaper," but instead, you and I spent nearly 6 uninterrupted hours on the couch? That was fun. But I'm still kicking myself for wasting half my weekend with you. It's really not your fault, though. It's mine. You're a great pastime, but I think it's time we start seeing other people. This obsession I have with you is just... well, it's unhealthy. When I should be working or writing or spending some time outdoors, I'm seeking you out and spending waaaaay more time with you than is good for me. I just need some space. I'm not saying it's over, I'm just saying that we need to pace ourselves. I need some more variety in my life. It's not you, it's me.
I hope we can still be friends.
