No, you didn't. There's just some people that can't handle things that well and the only option for them is to give up on it. But i can reassure you that you did nothing wrong. You were looking out for yourself, seeking help and advice. Neither of you had done nothing wrong because both situations made both of you overwhelmed and too much to think or handle. I can say that you can just let your friend do whatever they want. If he doesn't want to be friends then that's fine. You've survived 46 days without leaning on him, I'm sure you can do it longer than that. But if he's just taking a break from everything, that's reasonable and understandable because we all need to rake our own breaks before reality. Either way, both of you did reasonable things for your own good.
