Being a good listener does not mean giving advice. Being a good listener means giving feedback such as “I can hear that, that sounds rough….I respect you for that….I admire you for being so honest……I appreciate what you are saying”
If she feels she has truly vented and sorted out her issue with someone who was actually listening to her, then she will feel much better and will have unburdened some of her pain. You can try encouraging her also by saying “how do you feel about that, will you be able to follow through on that, did you give that enough thought?…..” By doing so you are guiding her to be in control of her own situation.
