[One day he hopes Spike will get it through his head that this really is all or nothing. That he's slow to commit or admit how much he cares but when he does it's complete, and nothing can drive him away. He's so reluctant to get close to people in any sense that he won't do it unless he's sure they're worth it and Spike clearly is. As for leaving it at that he doesn't want to pry, but he wants him to steer the conversation, to open up because he wants to not because Ianto is making him.]
