I don't think you should do anything else ((Jan)). Maybe her husband discussed the over attachment with his wife and perhaps they felt this was the way to handle this. I know it feels hurtful but try not to let it bother you. When we apologize, the other person might not be ready or they might accept it but still need to keep some boundaries. You shouldn't feel worried about unfinished business or closure because you did what was necessary by apologizing.
