Your girlfriend would need agree with it and feel comfortable with it herself. There are many alternatives for her in the sense of counselling.
Really there is no one best form of counselling and sometimes it is just a combination of the teaching from different counsellors, friend and time that help give an individual the hope and encouragement to let go of difficult past experiences and move on.
Do continue to be there for her being supportive of her. Realise that it is her problem and that you cannot solve it for her. You can only help her find her own solutions. Therefore invite her to look at, and consider this form of counselling. If she feels that it may help her she may still need your encouragement to try it.
If she is unwilling to try it you might need to look for other alternatives or wait until she is more receptive to trying it. If she doesn't want to try it then it is unlikely to work. Most every form of counselling or self improvement will work to if it is in harmony with the beliefs and expectations of the individual using the service.
