Hi ECWeather, welcome to Psych Central.

Hmm, in order for someone to be more helpful to you it would help if you shared what the event was that this other person continues to struggle with. It is very possible that this event affected the two of you differently, for her it may have been more traumatic and she is avoiding you not because you are a bad person but instead she still has not processed and recovered from whatever the event was. You cannot change the event, and how it affected her, but it's possible that you can have a conversation about it where it may help her to at least face it and work on coming to terms with it.
