You blame one because "she couldn't take your suggestion that she might be wrong".
You blame another because "she didn't tell you of needs that she had".
You blame another because you "constantly demanded that he tell you the truth about his quickly shifting positions".
Another couple must be angry with you for my sake, because they like me more than they like you.
It couldn't be anything you did. It couldn't be because you kept poking the bear, and are now angry because the bear bit you in the ass.
It couldn't be that maybe some of our friends only put up with you and kept quiet about it so as to not hurt your feelings.
Maybe your concept of your character being "lovable" wasn't as accurate as you think.
Maybe the suddenness of all of these people treating you "badly" is something that you should consider.
Maybe you should consider it a clue.
As in "Get a".
Maybe you should consider taking responsibility for your actions.
It's not really my problem anymore, darling.
