"Usually what people get out of confessing their feelings to someone is the answer to the question of whether they are reciprocated; I have that answer. It's considered rude to ask someone out, get a no, and demand a reason. I already have the 'no', so the only thing to ask about would be the reason, and 'I like you, I've picked up you don't feel the same way, why, can I change that' is an inappropriate line of questioning that puts a lot of pressure on someone. I am very curious about the reasons but they're actually not my business. There are people who'd like the information 'I like you, I picked up you don't feel the same way, let's proceed exactly as we were' but I have to spend the next century around him and if I'm wrong about thinking he'd like to know that, the downside is ruining a very pleasant social relationship."
