Instead of turning into an apology machine you should have just listened and validated. "Reading your comments, it sounds like you felt isolated and alone, is that the way I made you feel?" "Yes, blah blah blah" "I am sorry you feel that way, it must be very frustrating." Notice you are not apologizing for anything YOU did, and you are not even agreeing with her. You are listening to her feelings, and validating them. Period. Then you go about your day like nothing happened. Why? BECAUSE NOTHING HAPPENED. All that spew, it is a reflection of how she feels at this moment in time. Her feelings will change in a year, or a month, or a week, or 5 minutes. She loved you, and she changed to not loving you. Guess what, she can change right back again and probably will.
