Men often seem very complex as they don't talk as much, or show emotions as often as women. However unless the guy is a jerk, it is best to take what he says as face value. If he says he is sorry, then he is most likely trying to soften the statement he is saying. It is very easy for guys to say sorry, as it is required by us all the time.
Saying he wants everyone out of his life right now to me shows some depression. No one wants everyone out of there life. It would be my guess he wants to take things A LOT slower and see if you really care or not.
Stricktlydating is correct in him saying you probably have done nothing wrong at all. JDove is silly to think "he could be broke and embarrassed that he can't treat you well financially"
Maybe in the 40's through the 80's men were the bread winners, and still often today wedding rings are considered an emblem of status not love. "Look how big it is!" However with women progressing in this world the facts are that in the average house hold women make more than the man, even more so in this time of high unemployment.
This isn't to say he doesn't want to treat you right, its only to say you shouldn't be so close minded as looking at money as the issue.
My best advice, be his friend! Back off some, and don't stress!
