I agree with curley. You've basically said that you're fine with staying friends and that you'd respect whatever decision he makes even though you value his friendship. Your best bet is to give him his space as he requested. It's really important you respect that. I know it's hard but it really won't move things in your favor by repeatedly going to him about it. Time will go on and he will make his decision, if he hasn't already. If he decides to open up about his issue and remain friends, that'd be great. But I will gently mention too, prepare yourself for if he decides not to continue being friends. Friendships are voluntary relationships; no one can force another person to be their friend. As for the advice you've been finding elsewhere, keep in mind that opinions on friendship vary individually. Sure, there is a general consensus most of us have about them but there is still room for different ideas.
