Most Helpful Guy
It's understandable that you're depressed. He refuses to speak to you and won't tell you why. He owes you an explanation but it's not in your power to make him give you one. I strongly suggest that you stop contacting him. My guess is that all the attempts are aggravating whatever he is reacting to. He may see this as overly desperate and needy. I realize this leaves you with no options. You could contact his friends but they may not know his reasons and the acts might make him angry. You can't draw conclusions about his thoughts about the status of your relationship. You can only draw conclusions about your own thoughts on that.
